I'm not sure what the reproduction Z565s cost in the UK, but at least in the US they are about $90 each, which is about the best you're going to get for that price. This may be different across the pond. I will say, however, that the Z565s I have played with are very well behaved and have excellent HF response, making closed loop stability much easier.
Edit:
I have built an amp around Hammond 1650P (not an EL84 amp, mind you), and I would consider it to be acceptable. It is reasonably well behaved, but the HF performance is average, and it really doesn't like more than about 16dB of feedback, even with the output zobel and several other tricks to stabilize it. So the Hammond stuff, while not my first choice, is perfectly acceptable. But Hammond is Canadian, so that will probably cost about as much in shipping and import as the Dynakitparts, no?

Assuming that taxes and shipping aren't too bad, I'd go with the Z565. It'll have better HF response than the Hammond.
EL84 8k output transformer from Toroidy is only 56€ TTG-EL84PP TOROIDY - Transformateur: de haut-parleur | TME - Composants electroniques less than half the price 😀
I have no interest in this Company, but I like to spend my cash with the best quality for the lowest cost 🙂

Interesting... got to wonder if they're available in the US. Not like I need any more output transformers until I actually build some amps, but those look quite interesting.

Lundahl is expensive and high-end everywhere. Arguably the Lundahl input transformer is why the legendary Focusrite ISA 110 sounds the way it does- very clean, very accurate.
I'll be very interested to know how those toroids behave. If they're decent, then they could be a great value for those who don't want to pay the (IMO ridiculous) price of the Hammonds.
My only thing with toroids is that I find it very hard to make the amp look the way I want it to with them.

I'm going to buy a pair next month and put them on my A300 clone breadboard / harman that I know well to see how they work

Another vote for Toroidy ...
I have used EL84PP, EL86PP (custom wound, minimal extra cost, sound great), EL34SE (current project, also sounds great with no NFB so far).
Plus power transformers for the above.
I have some exotic iron I picked up on an auction site for when I have developed my skills and understanding, but the Toroidy transformers have been sufficiently reasonable for me to get a foothold on this potentially expensive hobby, so I am very thankful to that company.
