We just put a deposit down on an Aluma 7816R to haul our Subaru Outback:

Ours will be a 16-footer, but you might not need that much length. Some friends of ours use the same trailer to haul their Outback and gave it high marks.
With tax, we're paying about $5700 for the trailer new. The trailer itself weighs 1150 lbs and can carry an additional 5850. In general, you're going to get 3500 lbs of capacity for each axle (ours has two, obviously), but the weight of the trailer itself counts against that capacity. So you'll want two axles.
