I have pro-comp (SOA now), I am not sure that pro-comp would be much of an upgrade above anything, don't get me wrong I liked mine but they are very very rough. Where are you located? $1000 seems like a ton of money to me, I think I had my SOA performed for not much more than that (relatively speaking) not that I am suggesting SOA. Sorry for rambling but if you are at all mechanically inclined you could put on your lift in a weekend taking your time. I did mine in my garage with the help of a couple friends, then for the same money you could have some tools a better lift and a little experience too. Just my opinion take it for what its worth. If you do decide to do it yourself you will be able to get plenty of advice from this board, personally I would change spring hangers (to maybe slickrocks or something similar) and shackles (even stock height) at the same time as the lift, if I had to do it over. Just my opinion take it for what its worth.
