Well Allen,
I have about researched this thing to death and gathered advice from as many sources and reviews as I could find. Here is my conclusion for "my" particular needs.
PC4212.... On order from Coastal Tools as of this hour.
It looks like it will do anything "I" need to do on a "hobby" scale. After watching the videos I am convinced this is the machine for me for the $ invested. I believe PC got it right on this one. Yes, Keller looks like the absolute easiest but is limitied to through dovetails only as well as size and spacing. While this is not a bad thing, I would like more flexibility if I am going to spend that kind of money on it. They should at least offer the same features as the PC for the higher price. And yes, the bits are pricey, but aren't they all to some degree? My conclusion is based on not wanting or needing to spend big $ on a high end jig that I simply won't use that often or take advantage of all the extra little features they are capable of.
All of the name jigs out there appear to be good in their own realm of design and intent of use. I am not going to claim one is "better" than the other because that would be a most false statement. We simply have to explore our intended use and look for the machine that would come closest to filling that bill. Oh yes, there is some real krud "low end" jigs that looked like a real pain to even attempt to use and I immediately dropped them from my list of possibilities very quickly after researching them. I believe my choice came down between the Keller and the PC. I simply chose the PC for price and flexibility over the Keller. I believe both machines are an excellent choice, it just depends on what you plan to do with each and I did not want to limit myself to only one method and style. I also did not want to have to take night classes to learn to use one of the more complex and capable high end machines
This is one decision I am glad to have off my plate as it has nearly driven me nuts.
I thank those who contributed to this thread with input and advice. All were excellent replies and I thought there for a while I was going to end up with 2 or more jigs
