I am looking to start doing carbon fiber infusion and was looing for some input on a vacuum pump. I completely understand that you get what you pay for and if I was looking to do this professionally then I would invest far more money in a pump. However for the average hobbist how do you guys feel about this pump for carbon infusion?

free air displacement - 3.0 cfm
ultimate vacuum - 75 microns
stages - 1 stage
motor - 1/4 hp

Thought this might be better than the Harbor freight alternatives.

If you want to make some small parts and you are not going to make much products, a lott off pumps will do the job. If you are planning to do bigger parts or when you are planning to make more products in the future, I suggest to invest in a good pump.
