I'd not buy one ... certainly not in my current circumstance ... but it would be really cool to have such a machine. The biggest problem for me is that, in time, the novelty would wear off, the machine would go into storage, and then find its way to my next garage sale. But while the excitement was high, I'd be whippin' up soft serve for friends and neighbors frequently, maybe even have a party.
I'm sure you'll enjoy the machine and get good use from it.
