Need Help !!! Which would you recommend for a 20 x 24 shop? I am ready for a new dust collector and debating between the Shop Fox 3HP and the Grizzly 3HP. The Grizzly is less expensive and wondered if anyone had any experience with it, and is it worth the differance? Thanks for any help in making my mind up which way to go. Any other suggestions are welcome. Turn For Fun and don't eat the dust.
