Have a look om ebay at the HSP brand cars , we picked 4 of the nitro buggies and they are still going strong , sure they're not a tamiya , kyosho or team associated but for the price of one of those you could buy 4 or 5 hsp buggies .
They do a brushless version as well -parts are readily available via ebay and cheap to buy , the only thing i didn't like was the radio but as i was used to using a spectrum unit for my race car – it is easy to pick a cheap radio to bits . The range of the radio wasn't spectacular but we were using rechargable batteries so the voltage was down a little and may have affected this butwe weregetting a 75 meters before the safety cut off kicked in .
If you really want to but a name brand i would suggest a trip to a dedicated hobby store – not a toy store and you can usually findt them advertising in the local RC car magazines .
