Any of the Midlands will work fine - I have their bottom basement 5 watt model, which is fine for trail rides.
You probably know this, but there is no such thing as a LEGAL rig that will do both Ham and GMRS. A completely stupid rule. With that said, there are plenty of radios that will do both - just keep your GMRS power to GMRS spec, and have a Ham license if you're going to broadcast on those frequencies. Oh, and don't forget your GMRS license either.
I haven't noticed any two way radios of any type with BT, and I'm not sure what you'd use it for...
I have CB, GMRS, and VHF/UHF Ham radios. I want to install an HF Ham radio as well, just haven't figured out how I'm going to do the antenna, and what I want ain't cheap.
