You're not the only one DJK.
I've rewired a few Schuko type plugs myself and they're just a pain, especially when you're using .75mm x 3 flex and you have to ball the peeled conductors up in order for the terminal screw to bite down.
I also once wired a new Europlug to the flex of one my cassette players (it's 110/220 volt switchable). The mail-order distributor I bought three of them from to experiment from thought you soldered it to the wires. But no, you have to crimp it on.
I'm sure there are some rewireable one sold in the EU. There better be....just like we have replacement two-pin plugs here in the West. Can you imagine the skinny flex of a table lamp going into a bulky plug better designed for an electric washingmachine?
