Does anyone have experience or can provide feedback on a Porter Cable 7812 vacuum? I am looking to purchase a shop vac/dust extractor that I can plug the tool into. I see plenty of reviews for the Fein and Festool line of vacs, but don't see anyone mention the PC. One of the reasons I began to look at the PC is price and ability to use on drywall (only on occassion - the main uses would be woodworking and home repairs). Size isn't that big of a concern, but I wouldn't want anything bigger than the PC. Is the PC stable - not prone to tip over? Thanks.
