The bike a bought a couple of years ago and it was a Giant Sedona. It's a comfort bike and has been a pleasure to ride, super comforable, looks good, very light. You can get a Sedona for around $350 without the bells and whistles as my friend did.She only had the water bottle holder added. Mine cost around $550 because I added the light and the milage tracker thingy (my mind went blank on the actual name of that) anyway, that is something I'm glad I had put on. I could live without the light since I never ride at night. I rode (and still do ride off and on) the Sedona for building up my stamina and often if I'm riding with a friend.
Recently I bought a Giant OCR1 and it's fun for more fat burning rides. I still love to take my Sedona out for a nice long ride and just take in the scenery. Sometimes I take it out for an hour on Saturday mornings and just take a long ride, later I might take the road bike out and ride fast for a more focused workout. Even on the Sedona you can go fast if that's what you want, I would ride 15-17 sometimes, other times 12-14 was a good smooth speed for me. I could ride that thing for days, it's such a great bike. I don't think I'll ever sell it...well worth the money spent.
