Unless you can't find a basic 4130 chromoly frame to work with go for it. I don't think Surly is all that great. It's very expensive considering you can find 80's frames of chromoly or even lighter tange...
I honestly think 26 inch with drops is better than running cross tires...Wider tires offer great control and make burning calories a delightful chore. That being said if you get the frame new for under 300$ I'd consider it.
