I saved a few dollars, buying used on Ebay. I won't bore you with details,
but that didn't work. I ended up buying one at Home Depot which turned out
to be a lot cheaper than the used ones off Ebay. I looked for one with metal
pump housing. You can tell, the high pressure outlet threads are metal. It
has served me well, since then.

I would not get one less than 2400 PSI for normal household use. That
allows the cleaning of concrete surfaces. The water intake is also
important, but I would expect it would be about 3 gal. per minute at
that pressure. I talked to several owners before I bought mine, and
those who bought less powerful ones regretted it.
