I haven't done any electronics since I were a lad (this is a great
reason to get back intot it!) - In those days I made PCBs using
transfers and etch resist pens. Is the photo-etching expensive to get
setup ? I bet the results are a lot better .. I'll do a little surfing
and see I think.

The most expensive bit that you really need is a UV light box. Buy one
for (roughly) £100 or make one for £50. The rest (etchant, developer,
boards, plastic trays...) is pretty cheap.

You can get good results for minimal outlay if you have a laser
printer using the "toner transfer" method - you print your circuit on
the laser (it has to be a laser) and iron it onto the board, the toner
sticks and acts as resist. Search for "pcb toner transfer" or
something like that, there are plenty of sites detailing the method.
