You people have given me great advice before (grovel, grovel) so here I
am asking for some more.


I've made PCBs before but always as one-off projects using transfers and
etch resist pens. But I need to produce 50-60 now !


There are very much easier ways these days - by drawing out what's needed
on a computer.

My requirements are very modest...single sided, a couple of 14 pin DILs
and a few other components, size around 50mm x 100mm.


Does anybody know of a reasonably priced outfit who can supply small
PCBs ? Artwork would be supplied by me. In what form is this normally
required ?


I think I've seen firms advertising on Ebay who do small runs. Of course
that might mean 20,000...

Or should I go ahead get a photoresist kit and supplies ? I'm starting
from scratch here with a few working prototypes on veroboard.


Have a look at RS Components site for the options on small DIY production
runs.

One way is to make a transparency and use that to mask a board coated with
an emulsion then exposed to UV and develop. Then etch in the normal way.
There's now another option - you print to a special paper and iron that on
to plain PCB. Haven't tried that one yet.
