Personally, I would not. But if you do here are some tips.
1) PAY WITH A CREDIT CARD!!! (NOT PAYPAL!!!!!!!!)
2) Pay with a credit card. (Not paypal.)
3) If for some reason you do pay with paypal (Like a moron) if the item is not to you in 25 days, file a complaint with paypal and get you cash back. (This goes for EVERY prop purchase.)
The reasons are, if you pay with a CC, you can always dispute the charge if the guy does not deliver product. But NEVER let it go more than 60 days.
Paypal gives you 30 days to file a complaint. I say 25 as most scammers will fed ex you the thing to avoid it.
Also, do not EVER believe the "I have just not shipped it" or "I have had trouble" lines. All scammers will use them to get you to wait. And if you use Paypal and go over the 30 days, you might as well have put the money in the fire.
