Yes, but not that much for small things when i cant afford or no time for a quick PCB design for prototyping.

Last year I was studying and as a student we get broke, PCB making costs roughly R400 well it depends on lot of things, like how many holes/vias, how big is it, silk screened? and sometimes when they don't know how to add cost they also charge for the track width, it gets expensive.

So the easiest way is to get a strip board it just costs something like R30, theoretically and financially all problems are solved.

But in practical theory we know the lower the cost... the more are the problems, I did one design which consisted of Video signals, and I never got to finish the design, i had some ground noise somewhere, hard to troubleshoot, from that time I hated the strip boards with all of my heart.

But i wont mine to do some simple things on it (but not video signals or both AC and DC on it), like testing something quickly before i can spent my money and time on developing a PCB.
