Thanks Tex. I am looking at 4 or 5 bag sets. I went to a local store today because they said they had 5 bag, 1 gallon sets but it turns out they only have 5 gallon sets. I think the 1 gallon sets can do up to 2 ounces at a time, which is pretty much exactly what I need. I may just go order online now. I was hoping to buy local and do some extraction this weekend while the wife and kids are away.
Regarding the low quality hash from the 25 micron bag, I would make tincture out of that. I've been making tincture by soaking trim and small buds in 100+ proof alcohol (Everclear), straining and then refining by letting the alcohol evaporate, adding water so the trichs settle to the bottom, pouring the water off and then finally letting the water evaporate. Once I get that "hash oil" goo I add glycerin and a little vodka to suspend the solution. It works, but is a huge pain in the ass with way too many steps. Ice extraction seems like a much better way to go.
