From what I've heard they should be good. For the money though I went with a military (Turkish) action. Not quite as nice, but money-wise it comes out cheaper.
CD Mauser action: $350
Military mauser action:$40
+$20 Scope safety
+$35 forged bolt
+$40 drill/tap
+$80 reblue
Total: $215, and in truth I'm having the receiver reblued with the barrel (ER Shaw), so that's something that I would have had to pay for with the Charles Daly anyways. I also have a C&R so buying the Turk mauser as a project rifle saved me the transfer fees I'd have to pay on a Charles Daly action.
Now I'm also getting a lot of other "gizmos" for my project that drive the cost up (Huber Concepts skeletanized SS trigger, stronger sriker spring, lighter firing pin, engraved floorplate, etc), but those are all optional.
