That is a great price but looking at resellerratings.com I would think twice about that seller.
Do you believe everything you read online? Big Value has a 99.2% feedback rating after over 74,000 sales on ebay. You don't get marks like that by screwing your customers
You have to understand that with ebay ratings you might as well start at 99% as being zero, and then rate the seller on that last percentage point. So, this reseller is actually about a 2/10 rating... for ebay (of course I overstate but not by much). I wouldn't touch anyone with less than 99.7% feedback rating. But go for it if you want. Perhaps you'll be one of the almost 6,000 pissed off buyers from a seller with such a rating, however perhaps you'll be lucky.
It is certainly your right to limit yourself from purchasing from a seller with less than 99.7% feedback. However, if you bothered to read some of that feedback, you would quickly see that a good percentage of the negatives are from folks who are intellectually challenged, scammers or simply had unrealistic expectations. By the way, you may want to revisit your math
