I use the Airtronics RDS8000 and I've been very happy with it. I purchased it with an 8ch RX for about $150. That was two years ago.
Today I would recommend the SD-10G or SD-6G. I think you will be happy with the SD-6G for $159. Airtronics 2.4ghz technology is rock solid and much less expensive that competitive equipment.
If you want more info on Airtronics, seach the forums for related threads...there are a few out there.
