The 2.0 versions have been released so you can snap up Endorphin Pro 1.0 for $150 (with an additional 10% off that gets you down to $135) right now with free shipping. Sounds like the primary difference between the old and new versions is minor changes to fit and color. Since I'm a cheap SOB this seems like the perfect time to get them.
