I'm currently looking around for a good used vacuum pump to start vacuum infusion.From what i learned so far there are several type's of vacuum pumps ,Rotary vane, Diaphragm ,piston type ,and others.
I know rotary vane is used the most and diaphragm pumps don't pull as much vacuum .I want to make small to medium parts  as a hobby and maybe also sell some parts if they work out well.
I also like the pump to be quiet and last long enough.I rather buy a used one from a known brand then a new chinese one.
I'm  currently watching a few used pumps  :

One is a dual diaphragm pump from Vacuubrand  ,this is the MZ2 pump which has a flow rate of around 2 - 3 m³/h and pulls about 7mbar vacuum.This pump allready has a vacuum regulator and vacuum gauge .

The other is a rotary vane pump from Shimadzu GDH60 which has a flow rate of 50l/min and pulls 10-² pa vacuum.This pump looks brand new ,but doesn't have a vacuum gauge and i'm not too sure if this brand is something reliable.
It is made in japan and does use a Mitsubishi motor  so my guess is this is a good quality pump.

Both of these pumps are for sale cheap  both buyers don't really know what they are selling .
Then yesterday i found a brand new DVP LB.3 rotary vane pump for sale .This is the same pump as the one from Easy composites ,except the easy composites one is the LB.4 which has a flow rate of 4m³/h and the LB.3 has a flow rate of 3m³/h .This pump isn't that cheap but the seller asks a lot less then the retail price.
Anyone have any suggestions?

So i bought a brand new D.V.P LB.3 vacuum pump which is almost the same model as the ones from Easy composites.
Only difference is this one has a slighty lower pump capacity .
The seller selling this bought it in a lot and was selling it again,so i got it cheap-er for 150euro including shipping which is a great deal.
It only needs a electrical power cable,on/off switch and some rubber feet which i allready have laying around here.
