I'm asking for C$0.50 per pin for the memory upgrades, which is something like (very roughly speaking) EU0.30/pin, or EU30.00 for soldering a pair of chips. He may offer a better price at Amersfoort, since doing a bunch of them all at once will speed up any learning curve and likely take a LOT less time per unit than my one-a-week piecemeal throughput!

Cheers
