You have a lot of options.
Most importantly.....Take your time and dont jump into anything. Do your research on the seller. I have bought a few things off rc tech with no problem. Just recently I got scammed for 100 dollars for a motor. I sent the money and he never shipped the motor. The guy had 100% positive feedback too. I know a few more people that have got scammed recently too. You think using paypal is safe but its really not. I filed a claim with them because the guy never shipped the motor. The sided with me on the claim but they said there is nothing they can do about my money
If it sounds too good to be true it usually is.
Good luck on you search. Let us know what you decide to go with.
