Good find, thanks for the tip on the discount. I was close to ordering a rebuilt Robinair 15600 for $200 shipped, but ordered the JB DV-4E from Zoro yesterday at $237 brand new. Got a UPS e-mail, should be delivered today. Now...only 3 to 5 more weeks for my chamber, which still gives me time to find a toaster oven!!
Mal--below is from Curtis' web site, some of the pricing may be a little dated but not far off currently. If I thought i'd start running multiple chambers off a manifold, i'd probably have gone 6 cfm just for the headroom--but I don't foresee that happening, just small batches for personal use. Lots of used JB and Robinair vac pumps on the auction site, even some on our local Craigslist--but it's hard to tell what has or has not been maintained, they mostly have been used in auto shops, so they look the same on the outside...can't tell about the inside!!
