Thanks everyone!

The cheapest IC is the ISD1020 from smallbear, anything above that costs mental money where I live! What do I do, what do I do! 
One of the reasons the 1020 is cheap is that it is old and has less memory. Truth be told the circuit would be much simpler if I had used the 1020. Essentially
most of the external logic I have in the
Payback is inside the 1020. Hmm...maybe I will do a quick variation using the 1020. It may make the project more available to others who order mainly from Smallbear and help with the sales of the 1020 but the 1020 is becoming somewhat hard to find from other sources hence one of the reasons why I went with the 25xx. I would hope that if the
Payback became popular enough that Smallbear would carry the 25xx ICs as other projects use it as well but who knows.
Edit: I just noticed that the 1020 is not made anymore. I was thinking of the 1420. Silly me. I'll stick with the 25xx.
I got my ICs from Digikey. They have the whole family of ISD recorder ICs.
Excellent work Andrew, you certainly move a lot quicker than I ever do?!
There's some excellent features in your design which I wish i'd come up with, especially the ability to kill vibrato during playback!
With regards to the way in which you've achieved the vibrato, i'd actually come up with the same workaround independently. I don't know if you recall me saying my version was a dirty hack so I went back to the drawing board with it 
Goddamn nice design!
Thanks Jaicen.

The vibrato seemed kinda obvious so I am not surprised that you came up with the same thing too. I didn't like the optocoupler as it would have taken up room, be difficult to calibrate, and with the RoHS scare moving over to something that is commonly available was smart move.
Will this work with a ISD25120P? Im liking the sound of 2minutes record time. Thanks loads for the new looper! 
Yes it will work with 25120 but as Nelson mentioned and I point out in the "recommendation" portion of the article the long the time the lower the fidelity. I recommend either the 2540 or 2575 for performance similar to the 1020. 75 seconds is alot of record time hence why I decided to split it with the multiple message function. The choice is yours of course.
And one more time for the world:

Oh! The good old hockey game,
Is the best game you can name;
And the best game you can name,
