Do I buy the 1980s RGA? Cons: - Bulky - Untested - Old Pros: - Under $1000, could probably lowball - Quadrupole _looks_ like it&#39;s in good shape - No software to find - Powers on, that&#39;s a good sign - All cables and stuff are intact and included

I'm mostly interested in AMU 0-50ish and I don't need high resolution. It's mostly going to be used for bakeout (H20 @ AMU 18) and leak detection (He @ 4) and any organics are just icing.

Other options currently on offer: - $700 for a known good Inficon Transpector XPR with software on a USB drive. The included sensor head doesn't give a good spectrum, however, and it's a fancy XPR head, so it's not that serviceable. - $2000 for a working Transpector XPR2 with software - A bunch of cheaper options that are either known-bad, missing parts, include no software, or completely untested.

@North I haven't the slightest idea what this thing does, but I like when people I follow post interesting machines, so you should go for it
