that the 208 is a replacement for the 207 basically. The 207 will phase out at some point. They will (have?) introduce a 208rr the same as the 207rr.
So the 208 as Stew says is the new 207...but you may have to wait (or might struggle to find?) anywhere with 208rr's.
I'm having the same dilemma...but I've decided to go for the 207rr's, and leave the trials for someone else just now
