Sure, it's a good idea to read Amazon reviews carefully and weed out ones that reviewed a different model, had some sort of agenda, or don't know what they are writing about. None of those apply to my comments on the 314 @ Amazon though. I have a reasonable amount of woodworking experience and try to write balanced and objective reviews.
The 314 I brought home from The Tool Shed (Gvl. SC) had a blade that was out of parallel with the base edge by about 1/32" across the blade length exposed at full cut depth. I did some test cuts guided by a straightedge and determined that this condition would be a functional problem - rough cuts and tough time holding the saw against the edge. 1/32" may not seem like much, but it is for a saw with blades this thin (1/16" kerf) and small (4 1/2").
I took the saw back to The Tool Shed. The manager inspected the saw and agreed that it was improperly manufactured. He also agreed that the saw's design prevented effective and easy correction of the condition. He popped a second one out of its box for me, we checked it and determined it to be properly aligned, and I went home with it. Been a good saw since.
Maybe the first saw I got was the only bum one they've ever made. Maybe the second one was the only good one. I'm sure the actual situation is somewhere between those extremes. I recommend the saw to other woodworkers, but suggest that it be checked carefully upon receipt.
