I'm in the UK, so the shipping cost of anything would be more than it's worth I'm afraid.
Just a couple of notes on your own website:
*If you want a serious e-commerce site, you need a greater stock level.
*Are people really going to trust an e-commerce site made on freewebs ?
*Pics are awesome, and so are more detailed descriptions. E.g. What voltages are the motors that you're selling ?
*Checks and cash are not good for the buyer, as they are slow and have no "protection" for them. PayPal is awesome for e-commerce.
*Proper shopping cart software is nice for the buyer as it's something they'd be more used to using. Also makes orders easier to track for both partys.
I feel a bit mean for my comment before - If you're need some proper webspace drop me a PM.
