Another option you could consider is the OrangeRX brand receiver from Hobbyking which are compatible with the DX3C as they are DSM2 . I'm using a couple of these units in my cars and they work well. For around $20, you get a DSM2 compatible receiver that's almost the same size as the SR3500 micro receiver.
