Babe wheels are quite plain, but with a bit of paint and imagination can become works of art.
Be careful with buying wheels from ebay or craig's list ... some could be 'decorative' wheels (non-working). Others can have pieces and parts missing. Or they may not have multiple bobbins and replacement bobbins could be hard to match up.
I've sold a few Ashford traditional wheels from under $250. Folks come to me with a wheel they need to get placed ... I don't go looking for them. Ashford is a good brand and you can find parts and bobbins for them.
