Stumbled on this post when looking at an old mixer I have for doing streaming and what a pack of cork sniffers this thread found.
I thought I would respond for anyone else who is looking for some advice on similar desks, not really the OP as I would suspect they have already made up their mind on what they would do with the desk.
1. The Behringer gear is not the best and if you're using it for tracking, and you are any more then a novice, you'll hear that. However it depends on what you're tracking for, I originally used this desk for tracking demos to then take in to a pro studio to record with session players, so for this application it's 100% acceptable, as it is for live or streaming work, as there are so many other factors where the weaknesses of the unit will not be heard. For a student learning to record, again what's the problem? The OP said he was going to track just some guitar and sax, didn't say what context, so telling him it's crap is short sighted, if it's used for a professional recording, it may not be up to the task, but try it and see.
2. Behringer did have some major issues in its early days before building their own factory, since then their reliability has improved, but they still use cheaper components and housings, so I wouldn't be using them in hostile environments. That said, if they are well housed and cared for, they don't have any more or less failures then many of the other brands with better reputations, the one I have is 9 years old. And on reputations, it's easy to get one, good or bad, it's harder to break out of them once acquired, I think Behringer suffers here.
So to answer the OPs question, and that of any others that stumble on to this thread, I have two simple rules for gear:-
1. How's it sound?
2. Does it fit the application?
For me the old Behringer desk I have, and will use for streaming, has 4 XLR inputs with compression, built in reverb and USB out, so it fits the application. Most people will be listening via Facebook live or YouTube on PCs, laptops, tables and phones, so the weaknesses of the listening devices will be be far greater then the desk, so it will sound good enough.
