OK, great, thanks, this looks like the easiest solution so far -- the one
where someone else has done all the hard work :-)

I'll definitely look into it, and if I decide to use it and redesign the
board (it'll be SMD stuff all around), the least I could do is offer you a
board as well -- built according to your specifications, of course (.

Anyway, I'm very pleased with all the great responses so far. I'll take a
few days to check things out, before deciding exactly what to use.

Hello again Nico,

I'm quite interested in your offer, but perhaps my e-mail to your address
hasn't reached you. Please substitute 'spamtrap' with my last name if you
want to send me an a-mail message.

Thanks again, best regards,

Richard Rasker
