coil spring spacer and torsion key's for 2" lift?

I want to lift my H2 but do not want to dish out a minumum of $2100 at this time. I can buy the rear coil spacers (1.5"-3" of lift) and the front torsion key's (1"-2.5" of lift) with the extended shock mounts for $200-$250. Anyone know if this will do the job for now or is it a super crapy way of doing it and will I regret it? Thanks!!!
