this is a quite simple layout with fat traces. it's not hard to obtain excellent results with this technique in this case.
I've managed (through a lot of patience) to get very thin traces with toner transfer, but it's a tedious process.
I just took the challenge, and a week later I built my own exposure box.

if you need precision (and speed), use UV

I fully support the previous poster. UV is the only way to do anything decent.

The "kitchen sink" description might be a little misleading. Isn't it a bad idea to dump etchant and paint stripper down the drain?
