If the Kona Hoss fits your husband and is also at a good price then get it. If you plan on ridng primarily on the roads you can get some slick tires and maybe some bar ends. If you want to start riding around on fire trails or dirt paths its pretty much good to go.

If you and your husband are both new to bikes the most important thing is to get something that fits. A road or touring bike would be ideal if you are primarily using paved roads. If you both just want to get out and explore the hardtail mountain bike is a good all around bike. I am wary however of recommending craigslist to new people. If you do find something that might fit the bill then have an experienced friend go with you.

You might also want to check LBS. Right now would be a good time to buy as they are selling off old inventory and getting ready for new arrivals. Also some shops do sell used items and would be a better place to help you for future concerns if you do buy from them.
