This is the one I have, the fancy 9 in 1 function is really preset temperature and time, but it's great that it can go to quite low temperature for dehydration and proof, which I haven't used yet because I haven't baked bread for a long time.
Perhaps it would be nice if you could operate in the busy months only and take time off the rest of the year. But would that work for your staff to work for part of the year only? Plus, if in future, when you decide to sell, would you be able to ask for a better price when you only have part year business to show? Either way, whatever decision you make, as long as you're doing what you enjoy most, that's what matters.
Have a great weekend Lizzie!!
