I want a vacuum table!

[Tenson]

What do you chaps think about this pump? 8.0CFM 5Pa 250W REFRIGERATION AIR CONDITIONING VACUUM PUMP + GST | eBay

It says 8CFM (240L/Min) which is about twice the other pumps I've found on eBay and it's less expensive too. Too good to be true?

Can anyone say from experience if I wanted to cut out these parts below with a 3mm cutter, what sort of flow-rate do I need from a pump to maintain a good 'suck'? If I were cutting soft materials I could leave a very thin skin to keep the vacuum up, but I often work with cast acrylic and I don't imagine I can 'skin' that so cuts would need to be full depth. The advice above of using adhesive backed paper may help me here but I just want to get an idea about flow-rate.
