Hi!

These connectors are fine but not very cheap...
A benefit is that there are many manufacturers for that standard connectors.

That's not 100% correct as there are also prototype boards for card edge connectors - we used 
It in our company before we switched to the DIN 41612 connectors.

You can see some boards here:

But remember that these boards are not that common and higher priced.
So if you want to build a complete system it ca happen that the more expensive DIN connectors 
Together with the cheaper standard strip or vector boards are cheaper...
