Go for a return flow cooler, Jap brands tend to be the best build quality and fit properly. As everyone has said you'll need to trim the reo bar, it will still be there but you'll be trimming it down and cutting the shroud in the front bar that feeds air towards the radiator. $1,000 for a jap kit fitted sounds like a good deal. I was quoted around $1200 i think for a custom job but ended up buying a ARC return flow kit and putting it on myself. The ARC kit is really light weight not sure about the cheaper kits though.
