Being new to this as well, I can offer some first hand experience as well...
First, off these guys/gals really know their stuff - so if they say it's so, it's so.
One thing that is difficult to get used to from the start is the tension of the blade. Since you're using pinned blades, make sure when you tighten the blade there is very little movement. You should be able to take your finger nail and "pluck" the blade and hear a high pitch tone - if you are musical in nature, it's around middle 'C' (closer to Bb though LOL)
Next thing is your push - if you are pushing your piece too hard it will break the blade as well - I've broken 2 this way so far - there is a fine line between just right and too much. I also find myself still pushing too much. What I've found that helps me is to watch the blade - when I'm pushing my piece, I try to cast my eyes back and forth between ahead of my cut and the blade to see if I am pushing too hard.
In addition, blades wear out very fast - and I mean VERY fast. As a new scroller, I'm lucky to get through 2 - 3 small works before I need to change the blade. Things that tell you it's time to change the blade include: Smell of burning wood - it is slight, but you may smell a slight burning, smoking - also comes with the burning, blade is not cutting as it did when you started the project.
I notice that around the middle to end of two 3/4 x 6" Plywood piece projects, I need to change the blade - however I can get through 3 or 4 1/4" Plywood projects fairly easily. I've not started to use hard or softwoods yet, but hardwoods I am told are rough on blades as well
While I know the blades that come with the saws are not that great, they are good for practice. I still use mine to practice.
Hope that helps somewhat
