It's not really a deal: there's no trim on the FD, you can only shift one cog at a time, and there's no spare parts. I don't entirely blame them for doing it since they've gotta be way cheaper to make, but at the cost of giving up all the features that make Campy worth buying.
A buyer's guide:
Everything Chorus and up is safely UltraShift with the nice FD trim and the ability to dump through cogs.
In 2007 and 2008 (the "QS" years), the groups below Chorus were "QS Escape", so avoid lower-end ones that have QS on the front of the left lever body.
For 2009 and 2010 when the new hood shape came out, all the new ones both 11s and 10s were Ultra-Shift again across the board.
Then starting in 2011 they reintroduced Escape as Powershift on everything below Chorus. You can tell the difference by the font/style of the group name on the front of the lever blade, which changed at the same time.
One caveat: the action of the Escape/Powershift levers is significantly lighter, and some people prefer that over the features of UltraShift.
