As an owner and regular user of many 4 strokes; I have Enya, OS, Magnum and Saitos. Of all these (and all work well and give good performance) the Magnum wins hands down on value per unit dollar. It IMHO gives identical performance of the OS's and life span so far has been very good. I'd highly recommend the Magnum 4 stokes for the biginner especially as they are so easy to break in and use.
