Thanks for all the suggestions! Unfortunately, my local Craigslist has nothing at the moment--I'd have to drive at least an hour to check out anything interesting. That 4.5" new Wilton is tempting, but I think I am going to go with the Yost 750 DI after all. Under $200 with free shipping, and my back is liking the idea of my saw being a few inches higher.
To answer the post above--I posted here in Chainsaws since that's mostly what I'll be using it for. Also just ordered one of Homelite410's chain vises, and very much looking forward to putting this combo to use. But I will be keeping my eye out when garage and yard sale season starts up again.
