I've been looking these over today, $85 to $100 seems to be the sweet spot, including shipping (in the US).
Just be careful to get proper plug and voltage for your area, since it looks like this design is reboxed by many. The one he uses in the video is around $300.
The cheaper ones remind me of the Daleks. When I get mine, I won't be able to stop myself from yelling 'Exterminate' every time I press the lever.
I've tried a few of the pegboard/drilled hole types with shop vacs and they'll never produce vacuum in the timeframe to get good results. I bought plans and the wire for a heating element from a company that used to make small table setups. It's a big project to build and it the end, probably not to good for small stuff. I also have an industrial vacuum pump for resin, so I'm ahead of the game in that sense, but this little baby really seems ideal for $100 and making small parts.
