For a nice tower or woofer box, building your own is usually way cheaper than buying new but rarely significantly cheaper than scavenging or second-hand purchases. There are tons of designs, but in general just build based off the specs of your drivers and the area you'll be placing them and you'll be alright. For specialized types like electrostats, building your own is pretty much the only way to go unless you're ready to drop 10-20k on commercial offerings.
