I've used the Dacor Nautica WD. It was not a terrible BC, but it wasn't a great BC either. I used this BC to get through my OW and AOW certification, then I got rid of it on eBay and upgraded to a SeaQuest ProQD+ and never looked back. The Nautica would probably be OK for shallow tropical water diving, but I felt it was not comfortable or rugged enough to handle diving in the temperate waters of SoCal.
nk5 mentions the TUSA Platina Evolution. Although I dislike most of the gear that TUSA makes, he was correct when he said the Platina Evolution was a "real nice BC." It is ... especially considering the discounted prices they are currently on sale for. But, the TUSA brand (like Dacor) tends to have a "sissy diver" stigma attached to it, in the United States. I will have to agree with LUBOLD8431 regarding nk5's other 2 recommendations.
My real recommendation would be to bite the bullet, and shell out a few extra bucks initially and get a good BC to start, to avoid having to upgrade it after a few months (like I did). SeaQuest makes great jacket-type BC's, Zeagle makes great back-inflation BC's.
