Picked up a saw yesterday, Woodcraft, and the base adjustment shoes are different from what I've seen in every vid and other stores. Went back; they have two saws in the store, both evidently new to the store recently, two different designs. Which is the correct current production base as of Feb 2015? Exact same model numbers on the cases. Pulling my hair out here trying to figure out which is current. Thank you in advance for any input, also any input on why there was a redesign?
