More info from seller
I'd sent an e-mail to the seller and he called this morning. His name is Mark. It is a Kitchenaid Regency by Hobart. He doesn't know the year. It belonged to his single aunt, who was the only owner and used it sparingly. Thus it is in very good condition.
He acquired it a year ago from his aunt, but has not plugged it in to try running it. He said it worked fine for her. Mark has been storing it since acquiring it.
If you're interested, you can send Mark an e-mail through his Craigslist ad which I listed above. Give him your phone number and he'll call you. Or, if you'd like to call him, he said it was ok if I give his phone number to any interested individuals. I don't want to post his phone number on a public website, so if you want it, send an e-mail to me. My e-mail address is listed in my profile.
I'm guessing Kitchenaid portables are not that common?
