For your price go with a MX-3 by airtronics, it has what you will need. If you are planning on upgrading from the rustler to a higher end model that you plan on racing go to a high end radio. M11, Helios, 3pk etc. Buying the radio now will set you back but it's money you won't have to spend when you upgrade your model later. If all you're ever going to run is the rustler then the MX3 will be fine.
