Datamem sent to me through US Postal, it took 5 days to travel from USA to Australia - which i thought was pretty quick. They even provided me with a tracking number.
As I only ordered (and received) two chips, the postage was comparatively high. It was $28 US for postage. Still that made it $15 per chip all up, which is very reasonable and something I was happy to pay.
The ones I ordered were PGA - I'm using one now and it is working fine.
I did think about letting AmigaKit know about them, but I thought it better to let the Amiga community know first, and I'd be surprised if AmigaKit dont watch the Amiga.Org forum, so they probably know now too.
For those of you that jumped in and ordered some chips, I hope your purchase goes as smoothly as mine did.
