I'd rather have a scope than a logic analyser. But if you want a logic
analyser, one of the electronic magazines (I think it was Wireless
World) published a very slick multi-channel one (not a toy) a year or so
ago and this would be much cheaper to build than to buy a commercial
unit. Sorry I can't remember exactly which mag it was - I'll dig through
my copies at home and see if I can find it.

You need a 50MHz dual-trace unit - and make sure the probes are Ok -
they're quite expensive to replace.
