the t4 RTR is only about 230-ish. it has a decent motor (17 turn) esc, and servo if you get the race - spec version.that would leave you with 70 or so dollars to use to buy some batteries. i would NOT buy any battery UNDER 3000 mah. i would buy one or two 3300 packs from radioshack. they are 25$ each, a pretty good deal.
oops, forgot the charger... with that 70$ i would buy a nice cherger that will last. a duratrax intellipeak charger isnt that bad for the beginner, though new, they cost 60 - 70$. you could pick one up on ebay for 30 - 50$ used.
yes, all of this is a lot, but you get what you pay for! team associated is a very good brand.
