I currently run a couple of the new strato charged redmax trimmers but was kind of wondering about some of their older models. Like the BC2600DL and BC3400DL in particular. I would like to hear from someone who has run the older and the newer models to see how they compare. The main thing that I like about the older models is the metal engine housing and the six inch trimmer head. I would be happy to try one out if anybody knows where I might still be able to get my hands on one. Thanks.
