Regular wet/dry ShopVac works good for me- the only thing is, if it comes with a narrow hose (and I think most of them do these days,) it's well worth buying a larger one to go on it. It's been a while since I bought it, but I think the smaller ones are 1.25" diameter, and the large hoses are 2" or 2.5". The larger ones don't clog very easily, and have plenty of suction for just about anything.
