2500 light duty lift

im lookin for a 4 inch lift for my 99 2500 silverado light duty, something fairly affordable, any ideas?

Im looking at a skyjacker kit for my 1500, its around $1300. A guy I work with has an 02 ecsb 2500hd and he put the same kit on his, says it is great.

If you want my .02 worth... Get a 6 inch lift... You will be glad you did in the long run... They are not much more than 4", and most you can de-crank to get 4" if you really want to.
