i agree w/them too! ive done my own about 4 times now and its hard at first but you also have to think if something goes wrong, you'd like to know how to fix it later down the road than have to take it back and spend a couple hundred dollars to redo what you paid for the first time. you decide to raise it back up and you're throwing money away. it took me about 6-7 hours the very first time i did it but now i can do the back in less than an hour and the front in a couple and not using a lift just floor jacks.
by the way definitely not bragging here just making a point
