Advice wanted please, has anyone experience of the cheap Vac pumps as sold on eBay for about £50 (a typical advert is “Vacuum Pump Rotary Vane Single 1 Stage 1/4 HP 2.5CFM, Refrigerant HVAC degassing”)
I want it for Vac Bagging Composite (glass/carbon onto foam). I currently have dry pump but the vac it pulls is a bit to low. The spec of these looks OK but I would like to hear it anyone uses this sort of device before purchasing.

Sorry, i don't have experience of this item. In my past, I bagged blue cored wings using a pump from a fridge. Just connected my pipework to the intake side. The vacuum was regulated by a vacuum advance and retard unit from a car's distributor and a micro-switch (yes, that old).
