everyonedoesit.com has cheap pollen presses.I got a nice one for under 25$ including shipping.It will press about 1/2 to 1gm at a time into pellets the size of an aspirin tablet.And if you use a wrench to torque the ends down really tight,you can acheive a fairly hard cake.The more pressure,the more heat that is generated to "cook" the kief.If you want to cook it further,you could simply toss the press in your oven at low heat for a bit.Only parts not made of metal are the 2 solid plugs that press the hash.Those are made of acrylic and should be able to withstand being baked at low temp.
