I am looking at upgrading my table saw and was considering a delta ts350, affordable, not a ton of HP but cast iron top and wings. Okay fence (afaik). Then I got to looking at Grizzly's stuff, like the 0444Z and thinking well heck for 200 more I could get more HP and belt drive and what appears to be a much nicer fence. Is it worth it? Is the belt drive definitely a must have, and if so, why? I understand HP. Maybe I'm just looking for y'all to give me a justification to buy the bigger machine.
