300 + shipping. I just upgraded to a DBII so this is now taking up a very small amount of space that I need for activities. It works well. The screws it comes with are threaded for my MKV post so you may have to get different screws with countersunk heads. Also to note, it does not have any safety pins to prevent it from slipping out if the top stage is not tightened down. I never got around to replacing it and fortunately haven't had any accidents. Maybe something to consider getting too, to be safe and all.
Please don't make fun of my keyboard.
