I picked one up on sale at Target a few months ago. Works as well as the higher priced Yakima that I once borrowed from a friend.

Easy enough to convert to a jogger...there's a small third wheel attached to the boom which you pivot down, then attach the handle bar and off you go. Nice and stable too.

Between biking, rolerblading, and jogging, we've been using it maybe 15-20 miles a week, and it's held up very well. HTH
