Well either way you're looking at about the same amount of money. (for the spacer lifts, that is)
The toytec doesn't have all the parts included so you would need longer bolts.
The rough country doesn't come with AAL's, but you don't really need them anyways with this kit. That kit is pretty much done for what you're looking for. They're both the same price basically and you probably won't be towing much or doing a whole heck of alot of wheelin, so it doesn't really matter which one you go for. It just seems like the rough country would be the easier way.
I was gonna go this route too when i was initially looking at lifts. I was in a tight money sitch and couldn't spend the money for a suspension lift.
BUT... I took my time, researched and talked to a bunch of guys on here and around my area(Toku58's awesome and will give you any info you ask for. He's a god when it comes to this stuff. Along with Chris4x4) and decided to save my money and not be so quick to jump at a lift.
If you're looking for long term, you want to go suspension. Think about it. You're most likely gonna eventually switch to a suspension lift anyways. Not only due to the wheelin part of it, but also because the ride quality is SO MUCH BETTER!!!!
So, if you just save up some more and look around for what you REALLY want, rather than a quick fix, i guarantee you'll be MUCH more satisfied.
Your choice though, just tryin to help a brotha out.
