The buggy, YES! The electronics, NO! I would recommend getting a used worlds car from the for sale section here or ebay for $100-$150 (look for lots of spare parts & lots of wheels), a used transmitter & receiver (spektrum dx2s w/ receiver $50-$80), a new or used servo (Savox 1257 $65 new, $40-$50 used or a solar d771 from www.hobbypartz.com for $25 shipped), a new or used ESC & motor (speed passion reventon r with 17.5 motor $90 shipped new on eBay), new lipo (I like SMC form www.smc-racing.com, their 5100mah 30c is $24.95 or the 5600mah 70c is $39.95, turnigy from www.hobbyking.com can be a few $ cheaper, but won't last as long), I'm undecided on a charger (cheap ones from hobbyking or Hobbypartz will get the job done for around $40-$50, but you will end up upgrading eventually to a nice charger like a Hyperion eos720i net for $130 new or $75+/- used).

That gives you a range of $330-$555. At the low end you MAY end up upgrading the charger, the lipo, & the servo within a year or so, & having to buy more parts. At the high end, you should be good to go for a few years.
