The most frequent referred and most economical vac is the Ridgid WD1450. It is wet/dry and 14 gallon. It's about $115 at Home Depot. For a heavy duty vac needed at a workshop, the Bosch AirSweep 3931A is recommended. It has twin filters which clean themselves. It runs for around $525. Amazon usually has them at a cheaper price.
