Hi. I wanted to say that 95% positive feedback is a VERY POOR score! DO NOT BUY from anyone with 97% possive or less!
98% positive feedback and more than 100 feedback comments is the lowest feedback you should buy from. Don't buy from someone with less than that, especially as a newbie.
Remember, you are just buying from some person out there, not from Ebay. Read the person's auction carefully, ask questions about the item before you bid, pay on time and things should go well. But if things don't go well, email the seller and try to work things out. A seller with good feedback will work things out with you. But there probably wont be a problem if they have good feedback.
