I would not be afraid of JR/Spektrum. They were pretty much first in the 2.4g category of radios and thus had a few problems at startup. The amount of issues reported are incredibly far below the number of people reliably using their equipment. For every complaint on this forum there are tons of people flying big, expensive planes flawlessly with JR/Spektrum equipment.

That being said, the Airtronics SD-10G is $1200 worth of radio packed into a $500 (or less!) package.
