I highly recommend the Airtronics MT4. Been use it for 2 years now and it has been great. I am also using the Airtronics high torque digital metal gear servo in my SC10.2 FT, it is fast and strong.
For electronics, it all depends. There is a lot of good stuff out there. For an ESC I usually go with the thought of only buying it once and usually go with something that will allow me to change motors with the most flexibility. The stock spec ESCs are great and cheap if you only plan to run stock blinky class. But I usually look for something that will allow me to move to mod class later on. I'm currently running a Viper VTX10R and it has been great. Plus it has a 1 year warranty. It is a little on the pricy side, but will still allow you to come in under your 1000 budget.
