I put a 2" all spring lift on my 87 Burb, my usage is the same as yours. Not so much a daily driver, but a family hauler on weekends. It's a Rough Country lift. Four springs, six shocks, steering stabilizer and all hardware was around $700. Not a bad price compared to new stock springs, and it's still a height that the wife and kids can get into without the aid of a step. The ride is comfortable, however the shocks are beginning to get bouncy after a year and a half, and 10k miles. It's to be expected, they're cheapo shocks.
From the information I got back when I was researching, I found that a 4" kit can be had even cheaper, apparently because it's more popular. The Burb would look great with a 4" lift, but it's just not practical for my needs right now. I suppose it all depends on how big of a tire you want to run, and how much lift you feel you want to make it look good. "Good" means a lot of different things to a lot of different people.
I also added the ORD zero rates in the rear, to compensate for saggy butt. (the truck's, not mine

) It's really an optical illusion created by the 1/4 panel lines. The truck may not really be sagging, however it appears that way. The Zero Rates went in exactly as the instructions described, no surprises. They're well made, and well worth the money.
I ordered the kit directly from Rough Country, via phone. A Google search should find you the number you need.
If it matters, I'm running 32x11.5x15 tires on the stock rally wheels.
Hope this helps, and good luck in your decision!
