I have had good service from the Einhel wet vacs with stainless steel bucket. I'm on only my 3rd one in nearly 15 years and as they can be had for around £50 I consider that good value for money. I've given them heavy use too. They can also blow which I have found useful in clearing blockages in waste pipes sometimes.
One thing to remember whichever wet vac you buy don't do like I did once and use it to empty a toilet cistern containing one of the devil's own Blu disinfectant blocks. They froth up the water in the vac and will blow it out the exhaust. I wish someone had been there to see my face when I turned around oblivious to what had just occurred to see blue dyed water all up the walls, units and carpet
