I wasn't trying to start an OEM vs aftermarket debate. Just seeing what the general concensus was for my particular situation. Btw...I have done lots of reading, but it doesn't make me an expert. It doesn't make me as knowledgeable as someone who has rebuilt saws many times. That's why I posted for some guidance for my particular situation. I would hope that you could tell I'd done research on it already by the specifics of my original questions. So as far as which saw to use...no real difference except for cap styles correct? Pick the nicer one? If the crank bearings and seals look good, is there any real reason to replace it? The 044 looks pretty clean. Looks like lower hours than the 440. I didn't see the piston and cylinder that came with it though. It was cleaner and all the plastic was much nicer. Thanks for all the help guys.
