If the goal is to avoid the cost of $60 tubulars, buying a new wheelset isn’t going to be cost effective. Not only will the cheapest new wheels cost a multiple of that, the tools to switch out he cassette will cost close to $60.

Your most cost effective answer may be to sell the bike, and buy another used bike with clincher tires.

Or learn how to repair tubular tires.
