Mine are TSWs, very solid guns, accurate, reliable, a bit on the heavy side (around 38 ounces if I remember correctly). They are my favorite .40, but YMMV.
There was a 4006 for sale locally recently that was priced right around $450 with 2 mags, IIRC. It sold before I could get to the shop to look at it.
If you want it for the range or home defense I'd say you can't go wrong, but it would not be my first choice for a CCW.
