I rode a magna for some 10 years, but as I started riding long distances (40-60 miles) it became too uncomfortable. Perhaps out of ignorance, or low expectations, before then I never really noted any problem with it. I bought a Trek road bike for those longer rides, but then wanted something not that expensive for the casual trips around the neighborhood. I got a Forge brand bike (M Street model) from Target.com for $180 and so far am happy with it.
Forge frames are manufactured by Giant Bicycles. Another member here bought one, and was very impressed with its ride quality.
It would make a good beater
