It's not much of an investment. $10 on amazon. I bet you find at least a few areas where eye-balling it isn't cutting it. It is very very easy for your eyes to lie to you based on your surroundings. There is a video done about eye balling calories and it showed how two almost identical looking meals actually had a 40% difference in calories. I'll see if I can find the video when I get home.

Ok, I trust you know best, but for the sake of being a know it all, I'm going to say that is actually takes very little space (if you have a small kitchen/bathroom/a sink and some ventilation, that's probably enough) and very little special equipment.

This is what I would say the basics would be for you:

• Beer;
  
• Oil/Fat (you can just use cooking oil, like canola or vegetable oil).
  
• Lye;
  
• A crappy thermometer;
  
• A kitchen scale;
  
• Mixing bowls;
  
• A pot (to make a double boiler out of);
  Mixing spoons;
  
• A casserole dish, cardboard box, whatever, and plastic wrap to line it with, as a mold;
  
• A knife and spatula (technically cake turner) for getting the soaps out.
  
  It's really pretty basic/cheap stuff. You can use used plastic bags and tape as gloves, you can wear sunglasses as safety glasses. Just be careful with the lye. When you mix the lye and water, its going to stink a bit, so you need some ventilation for that. You'll need the oil/fat to get to 110 degrees Fahrenheit, so you'll use a double boiler for for (a bowl sitting on-top a sauce pan/pot is what I use).
