It looks like the Durban Pro 7 is out of stock, as Target doesn't have it right now and Amazon doesn't have it on sale.
I think I'll go with the Nova. I found a Downtube 9 on Ebay for $260 used but the S&H is $60 bringing the total to $320, at which point I may as well step up what I'm willing to pay for new. I get why he'd want $260 but the $60, which I also get, just totally sucks and makes the Nova, new, without the S&H, more appealing for what I need.
