GZ Motorsports Vac pumps

Looking at Vacuum pumps and saw something over on Yellowbullet about GZ motorsports vac. pumps (http://www.gzmotorsports.com/vacuum-pumps.html). The price on them is half of Moroso, but the question is are they any good and will they last?

Can't remember if it was that or the Aerospace that was junk...............I know the Moroso is a quality unit.

x2 on what Jon said some of the aeropace products had issues ..... everybody i have talk to say the GZ is great product and also the moroso

Thanks for the info. I had read about the Aerospace pump having issues, but hadn't been able to find much about the GZ pump. I know the Moroso is a good piece, but if the GZ is just as good, then I'm all for saving 1/2 the cost of the Moroso.
