My first saw came from a pawn shop. An old rusty red master craft that I paid $50, to much but it was an introduction into the craft. Used this saw for 3 or 4 months. Started to look for an upgrade. Limited budget so choices were a General from Harbor Freight, Ryobi from Home Depot or the Porter Cable from Lowes. Nothing worth looking at was showing up on Craiglist. So I started to look for reviews from people who were still using the saw 3+ years after the buy. It soon became clear that over time the PC was the winner. One other thing, after I bought the saw I started to look on you tube for tips and ideas and noticed a lot of people use this saw, or at least use this saw and post on you tube.
Like everyone else that drop in plastic insert was a problem, but easy to fix with a few pieces of packing tape. Next to my old master craft, changing blades is a breeze. No problem with vibration. Also think once I add in the foot pedal I will like it even more. After I have use the saw for a year or more will come back and write a follow up.
edit-(year of use follow up. While the saw was a massive improvement over the one I had, I would not recommend this as a starter saw. The top reason for me is the table. brushed aluminum which nothing slides, I also think if it was steel the added weight would cure other problems with the saw like vibration. Oh and that drop inset around the blade, grrrr. One of these next days going to replace this one with a better unit)
