I had a look at that, apparently not too bad on price and it appears to do what needs to be done, it provides the missing 'back porch' portion of the video signal.

I would prefer a tidier, but more expensive approach like this

Here you just remove the original ULA and replace it with that modern reverse-engineered version - that particular one is quite expensive though, they seem to have been available for about half that price in the recent past.

If you consider the current price to be reasonable, check with the seller because that item is sourced from New Zealand - if the UK seller has local stock, fine, but if it has to come from New Zealand there could be considerable delays due to current events.
