I have no idea what a DE is worth. If you are just planning on, one all a round gun, I would look at something in the 9mm caliber. If money is a real big issuse, I would look at a Glock or a Sigma. I allso would sell the DE out right rather than trade it in. I got a feeling it's worth more to you that way. The 9mm is cheap to shoot, plus you can buy some man stoopers for it too.
