i'm looking into getting a 1/8 buggy roller, and i have no idea where to start once i get the roller. i dont know what kind of servos to get or what engine or reciever or transmitter, i dont know anything, i'm not totally new to rc, but i have always bought everything rtr, this would be the first time that i would have to buy and build my own car, so if you have any suggestions on some moderately priced stuff to stick in a roller let me know, i really need the help

Wow...this is a big question. I guess the answer would depend on what you intend to do with the buggy (race or bash). Everyone will give you their own opinions but you have to decide what works for you and your budget. For a good entry level radio at a decent price, try the Futaba 3PM FASST 2.4 GHz. You can normally get the radio and recevier combo for about $200. It also has built in failsafe as a safety feature and no matter what brand you get, USE A FAILSAFE!!! you don't want a runaway nitro going crazy at full throttle....trust me!!! Next you need 2 hi torque, metal geared servos. One for steering and another for throttle. I would suggest getting the fastest and most powerful you can afford as nitros are heavy duty vehicles. Probably looking @ about $100 each for good servos. I personally have had good luck using Hitec Digital servos in my nitro buggys, truggy and Monster trucks over the years. Next you will need a .21 motor. Here's where everyones personal opinions come in! I would suggest sticking to a more reputiable brand like OS, Picco, Sirio, etc. You don't need to spend $400 to get a really good motor. Good motors are easier to tune and you can get help from others who may have the same motor and are experienced. Whatever brand you get, make sure you follow the break in instructions and use good brand of fuel (at least 20% nitro). Bryons, Trinity, O Donnells, Nitrotane are all good brands. I would stay away from Traxxas, Blue Thunder or other "off brands". Next you will need a tuned exhaust pipe. These are offered based on the power band you want (low end, Mid, and High end). This depends on the track and driving style as well as motor. I personally have been using the Jammin JP series of pipes (JP-3, JP-2) Expect to pay around $70-$100 for a good pipe. Finally, you need a good starter box and battery. Lots of options out there. OFNA makes some good ones that won't break the bank and the 12volt gel cell battery is only $20. I hope this helps you a bit, I know it is confusing to get started. I suggest you visit your local hobby shop and haver them help you out if possible. If no hobby shop is near by, you can always order from some of the good on line stores and they have 800 numbers where you can talk to someone and ask for advice. Of course, this website is a great source as well. Good luck!
