RN to BSN or RN to MSN? Online program info, please

I am an old RN and work in summers. I have time and am thinking of getting my degree-mainly for my own satisfaction. I have a BS from Excelsior (regents when I started) but all my credits are from various universities/colleges (not tests) due to my location when I was a student. I was a diploma grad initially. Most credits were actually for a BSN in nursing but are old credits so I used them for the Excelsior several years ago.

I'm looking at Excelsior and Western Governor's but am afraid places I might want to teach [part time) wouldn't accept them/hire me. The other options are very expensive. Any thoughts about colleges that are online, have good reps and may be flexible about accepting credit? Thoughts about an RN BSN vs RN to Master's would be appreciated.
