Spektrum SR3100 clones - http://www.targethobby.com/spectrum-...p-4162169.html

$7.99 plus shipping.

I have a couple on order but from what I've read they are perfectly fine DSM2 rx which will work with your DX3S...no they aren't telemetry either...but again $8...makes you think about all the money Spektrum is making selling them for $99.
