Recomended lift kit for 04 Taco

I need some help trying to decide which suspension lift kit to buy. I want a mild lift kit, 4" or less. I've done some research and found that since I have auto-locking hubs that I can't go above 2" unless I want to buy a 6" lift which comes with the appropiate hardware. I can't afford that and I don't want a lift that high. Fabtech has a 3.5" lift that is fully adjustable so I can set it to 2" and not damage my front hubs. I also looked into a SkyJacker 3.5" lift which is not adjustable, and they said that there is no problem with my hubs. I don't know much about either company, but Fabtech seems a little more trust worthy. They also agreed about the 2" limit. I don't know anything really about lift kits but I want to expand my knowledge. I don't want to spend money on something that's going to damage my truck. Any suggestions and help would be appreciated. Thanks
