They come up now and then. It seems that lately the same Rippers seem to be cycling through the BST. The price has stabilized at about $700-800 depending on upgrades and the body color. If it's a Ripper that's been reanodized in a funky color the price seems to be less. If it's something more desirable with upgrades, a little more. The prototype Rippers all seem to go for about $1000+.
