So yesterday my installer says he needs a fine saw for cutting some baseboard moulding. I discover he's talking about a Fein MultiMaster. I call a local Tool store and they tell me about the Fein MultiMaster XL and RS models. I send my wife down to pick one up for about $350. That evening and BEFORE opening the box I do a quick internet search and discover that the model they sold me, the MS XE 636-2 is not Feins latest model. Feins new model is the FMM 250 which offers 250 Watts instead of 180 Watts. The new model is variable speed from 11K-21K oscillations instead of only 2 fixed speed options of 12k-21k. New model is more Ergonomic too. So, what would you do?. I'm thinking of taking this back unopened and getting the new 250 model.
