Yeah. The oil free pump is nice. It costs almost as much as the freeze dryer though. I have a really good HVAC 2 stage pump that works just fine so I saved money by not buying a pump at all. I'm putting together a diesel fuel filter system that will pump and filter the oil while the vacuum pump is running so I don't have to change the oil very often. Cost of all the parts I need for the system is about $250. A lot cheaper than the $1500 oilless pump. (And still cheaper than the oil vacuum pump they sell with the freeze dryers. Note: the pharmaceutical versions they sell are identical to the home versions. They are just pre configured with a different firmware that has different default times/temps and come in a stainless finish) If you want to do hash, the narrow pharma shelves are perfect. If you have flower, get the home version shelves. (More space).
As far as getting one because you are having problems with RH% in your drying/curing process. Get a humidor/build one. You will need a humidor anyway if you have a freeze dryer because you need a way to bring up the RH of the flower after freeze drying it. (Easy solution is to put a humidifier/dehumidifier in a fridge.).
