Gee, I didn't spend nearly that much for my supplies to build boards.  I think Nick uses the Chuck Adams, K7QO method that is on his web site.  I am a huge fan of that method, and have made over 100 boards without a single failure.  After trying for over 20 years and failing every single time, I was amazed at how easy it is once you use Chuck's method.  Here is what I spent:

Laminator $25 Ebay

Samsung 2020 Laser Printer, $49 Fry's

Pyrex dish, $5 dollar store

Digital Thermometer, $8 Harbor Freight

Plastic clamp $1 for 6, Harbor Freight

3% Hydrogen Peroxide, $1.89 for 32 ounces, Lucky's Grocery Store

Muriatic Acid, $5 gallon, Home Depot

Steel Wool, $2 Home Depot

3m scouring pad, $2 Orchard Supply

pcb, ebay $7

Adds up to $105.89.

Guess you guys must be including the computer, lol.  I recommend that you attend Nick's session, you will learn a lot.  The best thing is that you will then be able to build any circuit you want to.  It is like unlocking the world.  72, Doug
