This weekend my genny tore right down the middle.

The first warning I had was my wife saying "Your sail is torn!" and as I looked up it split right along a seam, from the leech to the luff.
It's not a new sail, but it was in good shape up to that point. I live in the Baltimore area, and while there are several sail shops in the area, I'm wondering what the expense of fixing it would be over replacing it with another used sail.
I'm not a racer, so I don't care that much about perfect shape; but I have no idea what sail repairs cost, and what constitutes "beyond economical repair." It's a clean tear, no shredding that I've seen. Does that make much difference?
Thanks!
