You won't necessarily need a vice, Chris. If you don't particularly need the cash or space, I'd be keeping them until you do have the time to work on them. Most especially the Bucaneer, as they seem quite rare and are very sought after. A lovely, unique little funster. Airsporters are more plentiful and easier to come by, so whether to sell or keep depends on how much you like the idea of keeping and using it.
