That is a great deal. The Axiom subs seem to get good praise and the DSP chips (some models) looks to be a real benefit over the more typical amp+box approach. But there are many others you can find on this forum that make very good subs. Your budget will drive this more than anything, as price is almost unlimited on the high side, but the floor for quality is not. The used option is very good, but check it out first. It is easy to abuse a sub and drivers are mechanical devices so be sure it works before you buy.
