Dominants are pretty mellow strings, used in orchestras. I like Helicores, but most often we dress in the dreaded Red Label/Supersensitive/Old Fiddler steels.

The problem with what Mark suggested (other than the not being playable) is that even if you get a cheap deal, you will probably have to spend big buck to get it repaired and set up so that it is playable, and then what are you going to do if you don't like it then?
