if you get a kit you're looking at upwards of $700+ depending on radio equipment. most RTRs will require a better servo($80-100) and you'll eventually want FM. the engine will cost about $130-150 if you get a pullstart version which will be cheapest to start. i got the hyper 7 pbs from www.rc-mushroom.com which comes mostly assembled except the shocks and wheels, comes with a hyper .21 8 port pullstart engine, and no radio equipment. the buggy will cost about $420 or so i believe after shipping from hong kong and then electronics and starting supplies will be another $300 or so if you get the good stuff which you might as well do the first time. i got a 3PM, hitec hs5945 steering servo, hitec 635hb throttle/brake servo, and stuff like glow plugs, fuel, fuel bottle, glow igniter, and whatnot to start it out. make sure you go over and loctite (blue) all metal to metal contacts or you will start losing screws quickly.
