I bought the G0555 with riser block some 4 years back. This gives me 12" resaw capacity. The only 2 problems I have run into are the guide bearings became sticky after cutting some very fresh pine, (my fault, not theirs) and I switched to a much better blade, the Wood Slicer from Highland Hardware again my fault not theirs. I could go into great detail about the blades, but they have been discussed many times here. I bought the 1/2" blades and as soon as they wear out, the next ones will be 3/4" ones.
My saw is well powered, well vented for dust pickup, (could use dust capture under the table at the lower guides) heavy and well constructed. By now I guess you have figured out I like my Grizz. Good strong sturdy dependable saw. I have cut everything from 1/8" stock to logs up to 10" diameter. Now the logs did take much longer to get through the blade than the thin stuff, but the cuts were made with no problems.
As stated above, if you can afford the Grizzly, get it, if not then buy the best you can afford. You will never be sorry you bought the best tool you could. Better to cry nowq about money than to cry forever over a poor working tool, not to say the PC is a poor tool because it isn't.
