Walmart offers the Lifetime 44" Streamline Impact Basketball System for $67.99 with free shipping. That's $9 under our mention from last November and the lowest price we've seen. (It's the best today by $22.) It features a 44" backboard, telescoping height adjustment from 7.5 to 10 feet, 12-gallon portable base, rim, and nylon net.
