Eric -
It's not quite $100, but it's not much more. I have an Oscar Schmidt OU28T 8-string tenor that I got on sale from Best Buy (of all places!) last summer for around $120 new. I like it a lot - even sold my used 8-string Pono (for a lot more). Barablanca also has one and likes it too. Look around on the Web - I thought I saw one for $160. My only complaint is that I need to adjust the tuning every month or so, but it sounds pretty good.
