Homebrew PCBs

I have used a Brother HL-4040CDN for TT successfully a few times (even had some 8mil traces routed between pads of an SOIC-8). Some of the  traces were a little wavy on the longest stretches, but seemed to work. 
I printed a few patterns since I knew the first few attempts would fail.

I only did a few boards and then found A6 sheets of photoresist for $0.30ea. I now use the photoresist for etching and the soldermask. Its more expensive than a $5 roll of shelf liner, but the success rate is nearly 100%.
