Target Sports is probably the most affodable indoor range around at $9 for a half-hour. Being located near the epicenter of the entire metro-area, though, it can get crowded, so show up either in the middle of the day during the week or first thing on the weekends. They have an excellent inventory of weapons for sale as well as some for rent on the range including AK's and AR-15's... a ton of fun! They have many accessories, too. I bought a top-notch bipod for my hunting rifle there.
