So I will focus on board design to accommodate different chipsets and possibly panelise multiple boards for you to experiment now that we have got the qty to keep the price steady.
Confirming: a set of 2 versions of board will now be supplied. One will have re-clocker chips from TI, NXP (2-4ns) that are easy to source (or get free samples). The other one has the high speed Potsemi FFs (<2ns). The Potsemi one requires some layout considerations for high frequency switching.

I don't know the part name, number, etc, so I'd appreciate a link. This is what I get from Ebay, worldwide :

Potsemi | eBay wrong name eh ? ah... you mean the Potato Semi part...

http://www.ebay.com/sch/i.html?_saca...r&LH_PrefLoc=2 not listed.

and Google.co.uk

Google

I'm not into bonsai plants, and I don't want a Mr Potato Head cover for the iPhone/iPod I don't have.

Finally, I found the company site...

http://www.potatosemi.com/

and they link to their ebay store :

http://stores.ebay.com/potatosemi_W0...3aFQ3aSTQQtZkm

so, what's the part number please ? Thank you.

That means you will supply individual board for isolation and re-clocking, not single board for both functions? Have you tried the Potsemi FF for re-clock? I've followed HiFiduino's Mod but didn't work.

No. Two alternative designs with layout to suit alternative parts choices.
