Re: Perf board
A company called Crownhill Associates do a range of pcb materials for very good prices that range from 3mm to 0.2mm in thickness - single and double sided.
I've used the thinner stuff in a hole punch to make small 'disks' that glue onto another substrate for point-to-point soldering techniques.
It's also very easy to cut to any shape with scissors.
A roll of adhesive copper tape is also in my store for the odd occasion that requires some screening or particularly convoluted routing.
My only other concession to manufactured parts are a set of SOIC-to-DIL adapter pcbs for when I can't obtain the usual IC's in DIL format any more.
The last pcb adapter I purchased was an edge connector that allowed me to use 0.1" headers with a 0.7mm pitch ribbon cable (50-way) so I could remotely mount a small LCD screen on my SDR receiver.
