I've had my eye on this since it was announced last year and am about to place my order for one. The Source is a sealed countertop unit that uses a built in vacuum pump and heater to evaporate the ethanol from your quick wash extraction and then allow you to reclaim the alcohol for later re-use. The unit uses a Bluetooth 4.0 (BLE) smartphone app to control it and adjust settings including time and temperature. This means you save on solvent costs, eliminate fumes in the air and drastically cut evaporation time. I believe it only holds 250ml but you can top it off over time if you have more to process. For making shatter as I plan to do, you would leave enough alcohol so that it's still pourable and then transfer to your pyrex or silicone dish for the last bit of evaporation before heat or vac purging. I don't believe it's suitable for normal vac purging though.
For me I usually use about 500ml of ethanol per run which takes about 24-36 hours to fully evaporate off under light heat and a fan. With The Source I figure it'll be less than 8 hours. While the unit is a bit pricey I should be able to break even after about 15 runs or so which is less than a year.
It's currently available for $400 plus shipping for USA or Canada from The Herbal Companion. They claim to be shipping in less than 2 weeks, we'll see if that holds true but they use Paypal so at least you have protection.
Any thoughts before I pull the trigger on it? I've been on the lookout for alternatives but I've yet to see anything else out there like it at that price range.
