RE: Newbie help please
If you can get them to ship to you, you might also check ebay. You can get decent used Hyper 7s (both RTR or as just the rolling chassis without engine or radio) for about $100 if you are patient. Really, it wouldnt be hard to put together a decent 1/8 buggy setup, with a decent battery / charger and glow ignotor, for under $300 (for the buggy, engine, extra parts, etc).
Even further, you can also get decent GS Storm buggies for well under $100 from ebay, and they also have parts support. You might want to buy a Storm rolling chassis for less than $100 (shipping to Barbados included), a Toki .21 engine (which is $74 shipped), and an XR2i radio. The Storm is an older buggy, but it still has parts support (maybe not locally, though). It was my first 1/8 scale and it was a good beginner buggy. The Toki .21 engine is suprisingly good for the money. Most people who have them are pleased with them, including my Girlfriend. The XR2i radio system can be found on ebay for under $50 shipped (even to you), and is a decent FM radio with more than enough adjustability for a beginner. That would put you at under $225. Then you can spend another $25-30 on a gallon of fuel, another ~$25 on a rechargeable glow ignitorand another $30 on a rechargable receiver pack and charger, which should put you just over the $300 mark with everything you need to start up and with a new engine.
Let me know if you need links to any of these things.
Although, really, for only another $50 ($300 for the buggy, $50 for the ignitor and receiver pack) you could have the same thing except actually a new, more modern buggy that is completely assembled and ready to go.
