Not a fan of the mode selector (s-dms)

It might be suitable for a first time rider, but like i said before it will just add more steps to getting used to your bike... YOu will have to adjust gradually to each mode
If you are already riding around in SBGs bike w/o the mode selector, you will be fine without it...
Now on the other hand the 08s are very similar to the 06+, If you want an entirely different gixxer (better, some might add) look into a 00-03 gixxer... Those things are freaking comfy and beasts!!!
If you want the new body style I would say to stick with a 07+ gixxer

If the s-dms is something you really want then obviously the 08+
Are bikes expensive in Canada?
