Metal Pump questions

Has anyone tried or can compare these two metal pumps? I don’t really want to settle for a plastic mity vac.

Metal Mity-Vac: http://www.pump … od/stoframe.htm
Or
LAdist metal hand pump: | LA Pump

I can’t vouch for the mityvac but the pump from LAPdistributing is absolutely fantastic. Its durable, and it works like a charm.

Don’t know about the metal Mity-Vac pump, but my brass pump from lapdist is over three years old and still works like new.
