On a lark, I did a search for any user and/or magazinereviews on this board. I was on page 3 of google before I gave up.
The reason? Behringer makes cheap audio products that sound ok and are great for beginners. The operative word here is cheap. There are recording pros who stay away from Behringer because they sound cheap. The mic pres tend to sound brittle, and they're not that durable in the long run. My personal experience with a Behringer product is with a venue's guitar amp that just couldn't deliver during the gig.
That being said, I've seen the boards used in less critical situations, live p.a. for churches and parties. But for serious recording? I think you'd better look elsewhere.
