this is were I bought it about a year ago but it was only around $390 free ship back then. It looks like the price has gone up about $100 since. Maybe its from all the crackheads and tweakers steeling and recycling everything they can get their hands on causing the price of aluminum to go up.
it only has two positions up and down. Bad thing about the down position is the bars are right in your rear view but I manage to get use to it as it doesn't blind you completely. Similar to having a crack in your windshield but you adjust.
This rack is a great alternative if your bed does not have utility-track system. Yakima has a rack but it is fixed position and cannot be lowered.
I chose to haul my yak on the rack because I tend to load up the bed with gear and mountain bikes when I go camping. The bikes will eventually have a spot on rack next to the yak as soon as I decide which mount to get.
