I owned a Porter Cable PCB375SS (purchased from Lowes for $200) and I feel that it is a very impressive saw for the money. Very user friendly and the build quality is quite high, considering its $200 price tag (which includes a stand).
I no longer own the Porter Cable (I scroll with a DeWalt 788 Type 1) but I enjoyed my time with it and feel that it is an awesome value for those that do not wish to spend $500-$1000 on a scroll saw, yet want one that is user friendly and built well.
I've also owned a Harbor Freight scroll saw, and after using the Porter Cable and the 788, it feels more like a torture device than a scroll saw. Understandable for the price, but not something that I wanted to use for any length of time.
