I encourage you to check out the German made Fein line of vacuums. They are the best shop vacs I have ever worked with. They are available with HEPA filters and are also designed to be an integral part of a dustless sanding system used for dry wall work as well as work involving toxics and nasty dusts such as marine bottom paint and fiberglass. The basic model which I use was under $300 (model 9.55.13) and is the quietest and nicest vac I've ever used, and if returned to a service center within the 1 year warranty period, they will overhaul it and guarantee it for another six month, ad infinitum. Check them out at www.Fein.com .
