My opinion is forget electric, you get a short amount of enjoyment then have to wait 8 hours for the battery to charge, sure you can get spare batteries etc but its still a pain in the butt.
Nitro is easy and tonnes of fun, thats the reason it dominants the RC car hobby
Electric is faster and more powerful than nitro. Run times are up over an hour with LiPo batts and brushless motors, just have a few batteries for non stop running.
Nitros are cool, I have them and have spent big $$ on both.
RC drifters DO drift. If I were you I'd look for a used Yokomo, Associated TC5 or Tamiya.
I just sold a TC5 set up for CS drifting with a brushless set up and 2.4ghz radio complete with everything RTR for $250.
If you want to get into drifting and are going to buy used, buy one set up for CS (Counter Steer) drifting. 50/50 power distribution makes it WAY too easy and not look as cool, you'll master it too quickly and become bored. Countersteer drifting has more power going to the rear of the car, so you need to actually countersteer and use throttle control to drift (like a normal car).
DON'T buy HSP or any other cheap cars. You get what you pay for with everything in life, but that goes ESPECIALLY for R/C. They are reliable if you're smart and put your cash into good brands, but the crap ones will leave you frustrated and you'll hate the hobby.
There's a rc company in the us called Tower hobbies. They have good prices and don't charge to much for postage from what I have seen it normally works out cheaper the buying here.
I got a revo, a picco .26 max motor, a crowd pleaser body and a ridiculous amount of other stuff shipped to my door for less than a revo by itself in Aus from towerhobbies. They often have big discounts ($150) once you spend over a grand.
Tower is great, amainhobbies is also fantastic.
