MDI rear shocks

Has anyone used them/had experience with MDI rear shocks?
I need a set of rear shocks for my KZ, but prefer not to spend the $$ required for a set of quality Progressive shocks.
I ride this bike in a spirited manner, but not a peg-dragging fashion.

Any info would be appreciated; saving 2/3 the cost of Progressives would be good, but I would hate to throw away $75. I realize that they will not measure up to Progressive, but are they "good enough"?

those are kinda long,how long are your stock shocks?

The question is not of fitment, they make many sizes. The question is of quality; how well do they work?
Thanks, kk.
