A few members on this board have had very bad experiences with LFP, so you may want to stay clear...
I just purchased the xtreme motorsports (Ron Davis builds them) unit, I chose that one as it does not have any hangers visible from the front of the unit, as they bug the crap out of me. But it's an incredible looking piece just let me know if you want pics (sorry not on car yet), but I can snap away the unit on the floor.
The gords page linked above lists the dimensions of many of the popular h/e's on the market, so be sure to check that out...may help in your decision.
