Box purchased and dropped off at the new shop. I ended up going with Harbor Freight. Home Depot actually sells a Waterloo that is similar but cheaper and presumably of higher quality, but it's internet only with a five day delivery time. I'll use the cheapie (400 bucks) until it starts falling apart and then start looking for something better.

Thanks to all for your advice.
