Any of those brands will work, but remember if you get a carrier that uses roll on - off style loading, it wont work as well for performing bike maintenance at the track. I have the motojackrack and have been using it for 5 years, only having to replace the $20 bottle jack once. With the bike locked down on the rack, pulling the wheels on/off for tire changes is easy, (no worrys about dropping the bike off a stand)I use a tie down from the bars to the frame of the rack lock the pegs in and drive anywhere, the optional gas can carrier is nice too. I have a trailer, but still use the jack rack much more often. The bike sits up high enough, ground clearance is a lot better than with those roll on types. To level the vehicle I use supersprings, they do a great job I would recomend them a muddy bike and some gas back there can put a good bit of tongue weight on the vehicle...
