Motion Offroad is high quality and i wouldnt hesitate to buy from them. Rubicon Express is pretty good as well.
Now, don't buy a lift now knowing you want to go higher in the future. just save your money and buy 1 lift. i've had about 4 different lift setups, with a 5th different one going in this winter. i could've saved a butt load of money if i would have just bought the right lift. If you go any higher than 5-6in, then go longarms or at least drop brackets.
