I tried the super cheap CopterX unit and it was not something I could ever work out. Others though like it and I guess you can reflash the firmware now and it was $40 or so.
The Bigaole unit I have never heard of but it looks just like the HB800.
There is also the Robird G31 unit for around $100 that does all of this stuff, is getting updated, supports the Sat RX and provides vibration monitoring. Sold under a few names but in the USA this vendor handles it:
I'm on the fence on what to try next. Seems like as you move down the pricing point, you turn this into more of a computer fine tuning project. The higher cost units maybe just fly without lots of tweaking. That said, if you don't like tweaking you should not have copters...
