If it were up to me I'd go for the Airtronics, but then again that's all I own!!!!

Seriously, the RD8000 is one great radio and you won't have any problems with it. They are rock solid dependable, and if you ever do need to send it their service department is first rate!!! One nice advantage of the RD8000 (also the RD6000) is that they have a modulation selection which lets you use ANY manufacturer's receiver with the radio!!
Hope this helps
