It might be more than what you're looking for, but I actually went with Old Man Emu springs. They're $75 each (I think that's what i paid at the time) but you're looking at some of the flexiest springs out there. They actually give anywhere between 2.5-3" (I got right in the middle, 2.75). I went with actual springs instead of spacers because I knew I wasn't going to want to upgrade. I'm actually planning a 1" body lift, but that's because I want one of the tucked t-case skid plates.
4WD Hardware also has 2" springs, I think they are $400 for the kit (I spend $700 on mine because I got a front trackbar instead of drilling holes), with shocks and other stuff.
Personally, if I had to do it again, I'd get the OME again! They flex so much I have to be careful to not rub the fenders when I get near full flex (stock bumpstops). It doesn't happen that often, but when you only have 31" tires it's nice to know you have the extra flex for harry situtations... so far, I've been in only 1 situtation where the springs didn't flex enough, but it just so happened no one made it through the up hill either.
On the other hand, if you plan (or even have the thought in the back of your head) on upgrading later, get a budget boost kit, period! You really don't want to pay for springs twice.
With any lift you're going to have to worry about the driveline. When I did my lift, I had both axles significantly shift (I used a adj trackbar in the front and a bracket in the rear, with plans for a new trackbar too). I also had to use the t-case lowering kit, and I've heard that this is pretty much a hit or miss thing, some people need it with 1" lift, others have 3-4" and don't use it.
