It isn't real easy, but you could learn to repair them your self. It requires special tools that cost about $20. Having them repaired at a bike shop can be pricey, especially if you do it frequently.
Avoid cheep bikes with shocks. This is a bit of cynical marketing by the Big Box stores. People who don't know a lot about bikes are likely to equate complexity with value. Those are really cheap shocks on those, and they will not hold up for serious mountain biking, which is the only place I would recommend bikes with suspension. Shock are not necessary for road riding, even if you are big.
