Better alternative to AE XP3 SS?
 

So I just picked up 2x RC18r RTR without RX/TX. I have been looking at the AE xp3 ss combo since it runs for less than 50 on ebay but I can't find spare receivers for cheap (since I need 2). I wanted just one transmitter that I can bind to each rc18r.

So my question is, what other options are there around this price point that will let me run 2 different chassis with ease?

EDIT: I am now currently looking at an airtronics mx3 2.4 ghz as it still fits my budget. I want to get this tx, and pick up two micro rx. Does this sound like a good plan?

Also what micro rx works with this tx?
