My humble opinion -
Robinair 15500 pump with a ProVac chamber is your best budget value.
Cool, thanks. One other thing. How would I connect the tubing from my vacuum pump to the glass beaker? Mine currently has some screw on inlet ports. I'm using a Robinair Pump
The one I've been using works great. This one is marketed towards the marijuana industry for making concentrates, but its no different than any other vacuum chamber. The only difference between mine that that one is that I bought that vac chamber alone, and a Robinair 5cfm Pump separately. That first link wasn't an option when I bought it.
Several options available.... this is the best resource on the internet for the discussion:

You can get one at Harbor Freight for under $100 but I was able to get a deal on this one through my employer so I paid about $100 for it...

Thanks. I have Everclear in a spray bottle.
Here's my pump:

I've never run the pump for more than a few hours. Another problem I have is that I have no easy way to check the pressure when it gets really low (I'm on a budget), so I have a battery-driven arduino with a BMP183 sensor inside the chamber. Eventually the battery dies so I have a limited amount of testing time. I can fix that with some deep sleep.
dudee.. thats such a bad idea... the mason jar could implode and yeahh bad things will come of that.
get a vacuum oven:

BEST butane extraction tool (cant wait to see someone tell me otherwise):

this is a proper setup besides the oven is made in china and is finicky sometimes
VAC Oven http://www.acrossinternational.com/570F-VO-16050-16x14x14-19-Cu-Ft-Desktop-Digital-Vacuum-Oven-VO16050.htm im getting the smaller 1300$ one. only .9 cubic ft that one is a beast. 1.9 my dream. and vac pump http://www.amazon.com/Robinair-15500-VacuMaster-Vacuum-Pump/dp/B000O1C47M Done and Done. and of course some hose clamps and a bit of 3/8" tubing.
Well first off knowing what "oil" you actually put into it would help. Veg oil? olive oil? lol go for a 2 stage 5 cfm..... The robinair is great! http://www.amazon.com/Robinair-15500-VacuMaster-Economy-Vacuum/dp/B000O1C47M/
Yes. Get a valve core remover and a 3/8" hose. I can pull a vacuum on a system to 250 microns in less than 15 minutes. Here was my original set up. It's a bit pricey to get started but you can get it piece by piece. You don't have to get it all at once.
Vacuum pump
Core remover
3/8" hose
Micron gauge
I recently upgraded my vacuum pump to a 7cfm and have two 1/2 " hoses with valve core removers. I can now pull a vacuum to 250 microns in less than 5 minutes on average. Saves a ton of time when heat waves hit and you are running around like crazy.
