Cliff - there have been a couple of threads regarding that.
Here's the short. If you've followed my threads, I prefer to recommend "inexpensive" gear that I've actually used. Also, know, I'm a dealer/contractor and sell a lot of different brands of gear. Also know that many of those manufacturers, including Behringer, monitor these boards.
The Xenyx lines of mixers - great. I purchased one last summer so that while my A&H GL2 was being repaired I wouldn't be without a mixer. Guess what's still in my portable rack. The XL1600.
I also have an NU3000 and did have 2 B212D active speakers which I had to sell late last fall to pay some bills.
I have been pleased with the build quality and sound quality of the Behringer products I've used in the past year.
Remember, they're a tool, just like any other piece of audio equipment, has a place and a situation where it's appropriate.
When I picked up Behringer as a contractor/dealer, I did it to replace the Alto Pro Audio products which were dropped by Yorkville several years ago.
