Unless you plan on bombing around the desert at 60+, the TC kit is prolly more than what you'd want to spend. Last I checked, their base kit was right around 2K, and that was a while ago, and that is just the bare bones kit, you've still got to scrounge up the other stuff yourself.
On a side note to the IFS, you don't necessarily have to pay a shop to do the SAS for you, you can have them weld up the front hanger, and the shackle tubes for you (without cutting out the IFS) and then you can do the rest of the stuff (wrenching, cutting/grinding/torching the IFS) yourself.
