Hey, Everyone! I thought I would add my two cents. The worst strings I ever tried were Super Sensitive. The use of these strings makes shrieking your fingernails on the blackboard at the school house sound like beautiful music. For awhile, I used the D'Addario Preludes, which are ok for practice strings, provided you change them often. But more recently I've stuck with the Thomastic Dominants and a Pirastro E; they have become my preferred set of strings.
There is a violin maker in Williamsport PA, J.R. Judd who has these strings at an attractive price---I think I spent about $30 for the set of strings, together with an extra E string. He is listed in the MSN Yellow pages, and tells me that he will be having a Web site up later in August---when I get the web address, I'll post it for you.
Mr. Judd does repairs on violins also. He recently did a new peg job on my favorite violin while I chatted with him. He's a real craftsman!
Gotta go fiddle around.
