As above Van. The problem with 'satisfaction' or 'happiness' is as before that it's almost entirely relative, and based on expectations.
My wheezy old Robland 1KW bag filter felt great for about a week back in 1997, but I'd no idea what a high performing dust system could do. I didn't find out how much of a PIA a poorly performing system could be until I started doing some heavy planing and had the whole show bog down in wood chips and damaged workpieces. Also until my sinuses started acting up.
I still don't, in that getting the new system optimised involves getting stuck into R&D-ing set ups for all the different dust collection requirements/machines I have.
By the end of that it should be fairly clear whether or not my Pentz based system is a decent platform. (was a decent choice for development - one that doesn't contain inherent limitations that make achievement of acceptable performance impossible) Trouble is right now I don't even (beyond a fairly abstract targeting a high/safe/comfortable level of air quality) know what 'acceptable' means in many cases - my sense of that will evolve in parallel with the R&D.
That's at the technical level - I'm not all that heavily guided by financial limits. As in I've been prepared to put a lot of time in to studying and building a DIY system to get around the limitation that I didn't have a lot of free cash. Others prefer to and will happily plough lots of cash into buying commercially available equipment.
For some it's almost a disgrace to spend beyond a certain level on a dust system, doing so attracts a visceral response and even anger. Others are reluctant to put the time in to study the technology, or the time to build to save money, or both. Or cautious that they can't pull it off. Some become deaf in one ear, and hard of hearing in the other so far as the health risks are concerned. or are not much affected by dust. The prospect of spending beyond some limit likewise for some causes the same anger/fear as above.
In some cases the fear is irrational, in that they would if they committed find it was worth the effort, and that they can pull it off. Others might run into trouble.
Some of us (like me) prefer to put the time into planning up font, but hate to end up with all sorts of problems requiring resolution after building/installing. Others are happier to give it a go, and see high levels of debug as quite normal. The problem of course is that it's possible to make fairly irreversible errors - to end up with a system that contains limitations that block lots of options, and are expensive to resolve - is not a decent platform for ongoing development.
When we discuss these topics and the question of satisfaction comes up the one thing that's pretty clear is that we're not always comparing apples with apples....
