Right now, there are new 2007 Reflex Growlers and '07 Fred Bear Truth bows on sale for under $400 in this area.

I have owned 2 magna tecs.My first was a redline HO solo cam.The 2nd was a 2004 cam 1/2.I enjoyed these bows,problem free and they got the job done.$400 would be to much.I sold mine last summer for $200 to $250 set up.For $400 you could buy a Trykon,maybe even a vectrixon AT classifieds.There are some nice bows out there that can be bought for that kind of cash or less.
