I have a set of Reebock dumbells I bought from Target. They're 10lb, 5lb, 3lb, 2lb, and they have straps attached so you can add weights together (e.g. make 12lb, by holding both the 10 and 2lbs). Please call 507-884-9492 if interested, or email. $30 will add an exercise ball and mat.

The weights are similar to this:
