Sony Ericsson M600 and W950 dirt cheap

Boy have these phones prices dropped. Ebay seller X1387 have the M600 for sale at 189$ US and the W950 at 232$. The P990 is also cheap nowadays but it's price has stopped dropping at 329$. To think these phones costed over twice as much just half a year ago. Talk about a drop in value (makes me feel like a fool for paying close to 1000$ when the P990 was released last August).
