Many of us got the kit version back then for about $1k, net of shipping. I picked mine up from their factory.
You might find one of those used. They ocassionally pop up. New; you'd have to buy one from a DSL dealer and probably pay somwher near $3k. I really don't know. It's an awesome $1k horn sub. At $3k I would build 2 L/G horns. http://www.danleysoundlabs.com/products/subwoofers/specialty-subs/dts10/
