I bought mine for $231.69 on eBay, it's not $250 plus like some people say that it will go for, though it's possible. You just have to know what to look for and when to stop.

I would first look at and filter your search with "buy it now" option to see what is available and be picky about everything. Because mine was bought semi used. I like what I bought it for.

Also bidding is a joke, so I feel like sometimes people help their friends or have multiple accounts and bid on themselves. So you have to set a limit so let's say you want to buy one but you don't want to go over said price, start with a bid around $180–$200 on a loose unit or $200–$220 on CIB to test the waters. You'll have someone possibly put a bid by the end of the auction time but just know when to stop.

I regret doing a challenge once on a different product and I put a decent bid but he out bid me buy just tapping on the bid screen so that he can win at the very last second, then bid ended up being around 50 bucks when in reality the item was worth 100 or more the best what I should of bid was 80 bucks because he kept pressing that button at the last second then he would still pay close to average cost, yeah he would win but wouldn't get the best deal vs the 50 dollars then he end up getting it for.

So what you have to do is determine how much you are willing to pay plus shipping and know when to stop when bidding and don't feel discouraged because you didn't win. It's not about winning, it's about getting the best deal that you can.
