PSA: '05 X.0 Rear Dr. on closeout

Just a PSA folks: www.speedgoat.com has '05 SRAM X.0 rear derailleurs on closeout for $120 and free shipping. I think they still have both long and medium cage's available. Still pricier than the X.9 / X.7 stuff, but much better price than the $200 bones or whatever full retail was. And the '06 stuff is around $230 or so. Are there any differences between the '05 & '06 shizz?

The only differences I know of between 05 and 06 XO stuff is in the shifters. In 06, XO will offer trigger shifters and they are supposed to be so much sweeter than ever XTR rapid-fire stuff. I can't wait till I save up enough to get 'em.
