In the long run, it's much cheaper (and less hassle) to do things right the first time, so I'd say save you're coin and get the best setup that you can afford (and is reasonable for your goals).
It hurt the wallet (and VISA) real bad when I sprung for the MM Max Grip box, but it's nice to know that I'll likely never outgrow the suspension (except for maybe different rate coils, which is any easy swap).
Good luck, you'll be happy with anything from MM.
