I've got the DETC410 and I like it so far. It has way more steering than any other TC I've tried. I've usually been more partial to the Associated cars but I love my Durango. Parts are cheap, it's fully equipped with everything you need right out of the box, and I love the looks of it.
The only things I would upgrade would be steel or Ti turnbuckles for the camber links to replace the aluminum, and steel front outdrives if you're running mod.
A few nice things: the arms, hubs, and rear bearing carriers are the same left to right. Arms come in a 4-pack for $10. The bulkheads are are interchangeable front to back, as are the shock tower mounts. It also comes with swaybars and double-jointed front CVDs right out of the box.
Lots of options out there, though.
