8 Cup Pyrex's and a pair of microwaves, you can have a gallon of plastic coming out of the microwaves every 15 - 20 minutes (depending on how new/worn out they are and the power of them) 98% of what I make I already have colours formulated for so I mix the colour in before heating, add flake and salt after heating and dump it in the pots to keep it hot. RTM is right, it isn't perfect, it takes short adjustment period to figure out its quarks but once you have it down you can push a lot of plastic through it (Talking about the larger 2.5 gallon pots) running the right baits I can shove 12 - 15 gallons through it a day, not bad for hand injecting.
