You want a classical that sounds like a steel string?

That might be a tall order. You might have to go the MIDI pickup route (which on a nylon string guitar might be an even taller order) and then do some kind of simulation/sample playback setup.

Now, if you just want to groove on a reasonably priced classical, I can heartily recommend the model I bought about a year and a half ago from Rondomusic.com

The one I bought was a solid cedar top with a Shadow P7 pickup built in. I don't see they are currently carrying them. Contact Kurt at Rondo to find out if they will carry them again.

I paid $150 for mine. It sings nicely for a classical - a little on the heavy side for a classical. But it does not sound like a steel string guitar.
