non adjustables (ie: KYB, tokico) will run you anywhere from from 3-450 at most. I wouldn't pay more that 450 total for nonadjustables. Adjustables on the other hand will be a bit more (possibly in the high 800 range). Not really sure the figures but worth the money.
I have the Progress/KYB-GR2 combo, and it rides too stiff. If you like it stiff, then it's for you. IF not, i would go with Pro kit with Tokico, konis, or even Bilstein.
