Vacuum Pump recommendations

My breathers have puked oil on my headers and under my tires for the last time. I'm going to step up to a belt driven vacuum pump. I have a motor plate that I would like to mount it to. I have an ATI Superdamper and a single pulley to run my grapefruit size 80 amp alternator low with an AR Engineering kit. I'll have to find the single pulley manufacturer, but I think I git it through Mancini. Anyway.....what are people using? Moroso, GZ or Aerospace? Any issues I should be aware of? I will call all 3 manufacturers in the next few days but wanted to hear from people that aren't trying to sell me something. Thanks in advance . Crank pulley is from Doty Manufacturing.
