Amazon offers the SKLZ Pro Mini Hoop 7-Foot Adjustable Basketball System, model no. HP08-000, for $69 with free shipping. (Walmart charges the same.) That's the lowest total price we could find by $81, although we saw it for $10 less a year ago. It features adjustable height from three feet to seven feet, a breakaway 13" rim, 9" mini basketball, 33" x 22" clear polycarbonate shatterproof backboard, and sand-fillable weighted mobile base with built-in wheels.
