Ok so if you don't feel that you can do it yourself then the word cheap shouldn't really be in the conversation. I understand that you would like to get a good price, but you are talking about what will be holding your entire front-end together.
That said if your are on a budget then I would suggest you look at what you really need. Trail gear probably has the most affordable kits out there with all the extras included, but if you don't need to rebuild the axle, new rotors, etc., then you might shop just the parts you need. Hanger kits go for around two bills, springs depend on whose you go with, shocks, high steer, etc. My shopping list includes parts from 4 or 5 different sources and is well above what just a kit would cost me, but I have gone thru and picked parts for what I am looking to accomplish.
You could fab your own parts, do a RUF and some chevies, etc. And get out clean and under budget, but if you are going kit you will spend some $. Also most SAS kits are front only, so go ahead and figure one another few hundred for the rear. And regardless you will likley be regearing and buying tires.
Please don't take this wrong, I just want to make sure you have a handle on all the pieces before you jump in.
Keep us posted on how it all goes.
