With that criteria, the VTF2 would be my first choice. It does go on sale from time to time, but the discount isn't very big, so I wouldn't wait for that. The Outlaw Plus sub just left its sale price, and it does not go on sale as frequently, but when it does its is usually at a very good discount. It will be awhile before that one goes on sale again. The SVS subs rarely go on sale that I have seen, and I don't think the 1000 series will be on the level of the SVS and Outlaw so I would skip those anyway. Those subs are for when you need to make a concession for size, but if you aren't as size limited, go with the bigger subs.
