Rancho makes a 1.5" leveling kit for Tacomas, uses new coils and shocks, the ride is very close to stock. If you want to go higher later you can use an additional 1" spacer with the coil.
I've had mine on for 2 years, 9 mos of that with a 1" spacer and I still like the way it rides, a little softer than a stock spring with a 2.5" spacer.
IF you are not going to be doing any serious off roading then I would say the Dons are kind of a waste of 900 bucks. If you just want to level the front out then I would get a spacer. You can pick those up for less then $100.
