actually, i have alot more into mine then most people would, because we bought twice the metal we needed, and this is my second frame. i got the motor for like 270$ which is a great price, the tav is somewhere around 200$ the line is 100$ for 600 feet. plus the fairlead, axle, sprocket, the aluminum for the spool, the mounts for the sprocket and the spool, the chain, and the berrings, thats pretty much it, plus you need the tools to build it, and all the nuts and bolts,
if you really watch your money, and shop for prices you can build a really good one for about a $1000.
ive got some links that are still book marked that ill post here for you

the other parts, you should check out different go kart supply sites, thats where i got my tav, the sprocket, and the chain.
also from 4wheelparts i got the fairlead for like 25$after shipping,
i wanted to buy one done, and my dad said he could build one for way cheaper. and after everything was ordered and i had all the parts, i realized i could have bought one that was already done. i wouldnt HIGHLY recomend finding ALL of your parts before you buy any, also, is it worth your time? ive got so many hours into welding and grinding that its rediculous
