I don't know what the deal is with the 2.4 rcvrs, but the FM PCM rcvrs I've had repaired were on a set fee type deal and it was a no brainer, $25 against the cost of a new one for $85-90. Thsi has been years ago and the wait may now be a factor too, I had mine back in a few weeks back then.

Its worth a call/email to check out, then you'll know what you should do -
