I'm with Steve... why a nosedragger? Few classics have a nosewheel. Other than the Ercoupe, and some rare variants of the classic taildraggers (there were a very few nosewheel Aeroncas and Taylorcrafts, but most were converted back to taildragger). Another option might be some of the ultralight derived planes like Challenger, Quicksilver GT400 and 500, etc.
If you learn to fly a taildragger (it's really not that hard) you'll likely never go back to training wheels...
