Ebay shoots crack everyday and not just meals times. I've been severely turned off by ebay. I use to like going there to check on gear, but now everyone and their mom seem like they are in a business on ebay, trying to sucker you in to think what they are selling is a good price. And they keep it there until you see nothing but it, and can think nothing but that price. That's how they work. They play on your weak strings and if they get bites they like to play games and raise the prices, drop them a little and raise them back up.
All you need to buy is the 'ebay business strategy courses' to learn how to "control" the situation or price setting.
What's sad, is ebay business sellers have set the "Market Value" of synths ( not to my in my mind though ) and it's not the place it use to be when random sellers would list things and you could actually get a good or fair deal. Now it's one big poo poo platter.
