Amain has the 1/10 Lightning series on sale for 215. I've been contemplating picking one up as a 1/10 brushless conversion. It's probably one of the best RTR packages for that much money. $85 in change will get you a glow plug ignitor, fuel, batteries, fuel, and a fuel bottle.
Do your research after determining what your budget will bear. Do you have $300 to spend? Do you have $1000? Once you figure out what you can afford, go to your local hobby shop, since they will be your first support for parts and supplies. See what they carry, see what features you are looking for, and make a decision based on the knowledge you have accumulated.
Keep in mind, since you're new to this, you also need a radio, fuel, charger, and all the other peripherals involved in running R/C cars.
