Well let's get the shit out of the way... Behringer sucks. Feel better?
Kidding aside, there are several reasons to not purchase or use their products, mostly involving their legacy business practices, poor rate of product longevity, non-existent support and playing fast and loose with the intellectual property of others. I have a problem with all those things, but they don't keep me from being an interested observer nor did they keep my boss from purchasing some of their products, as he was only interested in the cost of acquisition for some specific uses. Most of those items are either in a pile of broken/dead stuff, have been sold off, or thrown away.
But if price is the primary motivation, you are the sole operator of the equipment and have to justify your purchases only to yourself, then
I think you should buy whatever makes sense for YOU. And that's the bottom line, really.
It's not something to get up in your face about, these aren't grave personal failings; you make the decisions necessary for you and your clients, and in fairness to Uli, the company appears to be making a concerted effort to rectify the lousy support and perceived quality issues, beginning with the X32. Time will tell.
Have fun, good luck.
