I actually attended Del Mar for three semesters before having issues with a psych instructor, so I did the excelsior thing. It worked great for me, and worth every penny of the 5k-6k that I spent. I finished the program in 6 months and graduated in Dec. '02.
The downside to Excelsior, is the 3 day clinical. Alot of places seem to frown on no clinical education (I assume that that is the problem with CA). The first hosp. I worked at, the recruiter was all excited that I wanted to work in CVICU until I told her I graduated from Excelsior. I think the only reason that I got the job was because I had worked there as a tech. With your experience as an LVN, you might not have this trouble.
Good Luck either way.
PS. I've heard talk of an LVN-RN web based program in Austin, but I have no idea where.
