I don't own one, I looked at them pretty close a few years back, was planning to buy one when a used minimax popped up in my area real cheap, so I went that direction. I think the PM2700 is a pretty solid offering in the "basic" small commercial size range. The fence is good, it has some nice features like built in mobility, built in digital height gauge, aluminum fence plates with hold down accommodations. Its an update to their PM27 line which I have used quite a bit. The 27 is a good solid work horse for a lot of small shops, no frills machine that works well for cabinet doors and light molding work. They didn't always age well, I used a few beat up varieties that had developed out of parallel issue with the fences, or some chatter as the bearings wore from use at or beyond intended capacity, or slop in the height mechanism from who knows what that makes precise height adjustments more challenging. I've also used a nearly 20 year old PM27 in another guys mostly one man shop and it was kept in such good condition it hardly felt like the others I had used, real tight and precise.
Honestly, I think the decision to go with a shaper and feeder is ultimately more important than which shaper you choose. The tooling is probably the more important decision. Relative to your current indicated use, 5pc cabinet doors, almost any shaper 3HP and above is capable of delivering a decent performance. I prefer 5HP for the marginal added cost, easier at resale, and this is America where bigger is always better right!
You may appreciate the extra power if you ever get into passage sized doors or molding work. For me it comes down to ease of use which is largely related to the fence. You don't make money fussing with a set up, you make money pushing wood through, so you want the set up time minimized. I'd look for precise tool less fence and hood adjustments, easy speed adjustments (if that is something you actually require), ease of spindle change. These are the places the cheap imports really fall apart. I've used a few at work that I wont name here, the fences are abysmal, the speed changes are absurd, changing a spindle takes an act of congress and some bandaids. The PM2700 has solved all these issues. The spindle change issue is a non event in many cases, I've seen shapers never get changed from 1 1/4". But sometimes in the small shop you go 3/4" bore to save some valuable funds, especially at the start, lots of guys evolve away from the 3/4" size once you learn how much smoother the bigger diameter cuts, others are very content with 3/4" bore. So its a personal decision, if you need different spindles, they should be easy to swap. The one issue they haven't solved is spindle speeds...the 2700 has only two speeds, 7500 and 10K, and thats pretty fast for a molding head or a big panel raiser. They should have put something in the 6K rpm range at least, so thats a draw back and a limitation if you get into bigger cutters, like over 5 1/2" diameter.
If you are going to spend close to $4K plus feeder on this purchase its probably a good idea to check out your options. That puts some more industrial used machines in range, not a choice for everybody, but definitely worth consideration. Most value priced used industrial tools require at least some work, cleaning or tuning. You trade sweet and time for lower cost. You sort of have to predict the future, will your range of work grow over time? Could you use a tilting spindle or is that a waste of your money? Will you use a sliding table, or is that a waste of space? Rod suggested the fully equipped modern euro shapers, I really like the versatility they offer but don't consider those options to be essential or their purchase a forgone conclusion for every wood worker. Sometimes a good basic shaper that spins a cutter is just as much as you need. I have a small slider on my minimax, it never gets used for cabinet doors, but for lots of other things I do it has proven invaluable. I can think of a few cases where a tilting spindle would have been a great help....but for basic cabinet work? You might actually forget its there. Before you make the purchase you might want to reach out to some professionals in your area and check out their set ups, maybe even find somebody with a PM2700 and see it run, at least go to see one in person at a vendor if possible, check out other options too.
