We just bought a brand new 2010 Featherlite 2 Horse Bumper Pull for just barely over 12K. I definitely wouldn't pay 7 for that trailer, there are just too many good ones out there for sale.
I would definitely check out www.horsetrailerworld.com
It is a great site full of trailers to look at and compare. Also, be willing to drive and get your trailer. The people that bought ours came from Pennsylvania to get it, my parents met them halfway in Cincinatti.
