Thank you for the reply,
The price difference in the UK works out about 25 USD.
I knew they were the OEM for C.K but wasn't aware they also were also re-branded as Elora - I think the model would be the 4630-f e 2k, unfortunately these are approximately double the price of the Schmitz, but worth keeping an eye open for.
I think the tapered head look more appropriately designed for electronics, but I know some people prefer the stronger oval head style.
