Specktrum Receiver

Hey just wanted to know,i just upgraded my m8 radio to 2.4ghs. with a
specktrum receiver sr3001.I need a second one for my other car.My question
is ,can i use the sr3000 receiver and use it with the sr3001 module,will it
work ,or do i need the sr3001.I check on ebay and all i see for sale at the
moment is the sr3000.Have only seen a few of the sr3001 try to bid but lost.
