I threw $2100 at my aus spec sprinter with a Whiteline (www.whiteline.com.au) kit. Shochs/Springs/Swaybars/lotsa bushes for front and back. Chucked in the rear suspension with a mate (no expertise reqd). Havn't got to the front yet but the turn in and handling on gravel and bitumen is pretty good. Id recomend it.
