IMO, there is no better itch to scratch than the "lift itch"
CST will give you 3.5" lift. Once you start adding coilovers to the CST, you're looking at 5-7" lift, depending on how you set the coilovers. Or, you can keep your stock shocks with the CST's, and just have 3.5" lift. Unless, you are just going to install coilovers and set them to 0" lift? That would be cool, but a bit overboard in my opinion, if you aren't offroading. But if ya got the cash, go for it!
Also, if your $3k budget includes wheels and tires, you are already over budget. Wheels and tires gonna run you $1600+, depending on which way you go.
If your $3k budget is just for the lift, you can count on about $900 for the CST, $1k+ for the coilovers, then about $400-500 for the shackles and longer shocks for rear.
If you can skip the coilovers, then I think you can get it all done for close to $3k, with new wheels and tires. $900 for CST, $500 for shackles and shocks, $1600 for wheels and tires. It can be done, if you can just cut your costs a little on the wheels. Discount Tire Direct has some nice wheels that they make/sell in house for around $150/wheel, which will allow you around $1000 for tires, which is very doable. Actually, you could get a set of 295/70/18 Nitto Terra Grapplers for around $1k, then a set of the MB TKO for around $560, and DTD may be able to cut you a deal on the package.
If you are wanting to go taller, like CST + coilovers in front for more lift, you're gonna have to set aside a little more money to bring your assend up a little higher.
Do it! (then post pics)
edit- oops, didn't realize this was a poll
I don't know anything about either, so I'm not voting...but I'm sure they are both good.
