The Denali will require some adjustment up front, but it's likely to have fewer problems initially than any of these used bikes. However, it's got inexpensive parts that will wear quickly, and you'll probably have to tension the wheels properly sooner than later.
That's a great thread, btw, on the commuting forum. The Denali has really scary handlebars: to make those MTB twist-shifters fit, they cut the bar in two places, add the shifters and 'glue' the bar together again. No thank you, an unpleasant surprise waiting to happen...
