Apparently being picked up this afternoon. Seller's a lovely bloke!
I got the QPlacer he also had listed (and a second one without a head) - item 173317779698
They're clearly from the RV family, but quite a lot heavier & sturdier (and a Cartesian gantry), with hopefully a bit better accuracy and speed, as well as a substantially bigger working area. Unfortunately they've had to go straight into storage, as my new unit isn't ready yet, but I'm sure they'll be lots of fun later in the year!
