What @dbr says.
The scoring function is designed for very fragile laminates. These days laminates that are that fragile = cheapest of the cheap (so bad it's really hard to find them anymore). With pretty much any plunge saw as long as the front rubber piece of the rail isn't worn and is placed so that it is sitting on the work piece not the offcut (hope that makes sense) you're good.
With good quality boards a bluntish blade won't make too much of a difference, to give you an idea; one of the incidents that made me stop taking on apprentices was when I was doing some floor to ceiling book cases in specialist veneered MDF (about £350 per 10' X 6’ board) My apprentice somehow managed to put the saw down onto my rails and cut through them blunting the blade in the process. I couldn't find anyone nearby that had a replacement blade or rails in stock and was dreading making my next cut, but as long as I let the blade do the cutting instead of forcing it the cuts were all prefect in almost every way, the only issues being the cuts took longer and the end grain of the MDF was more prone to burning.
