Yes Jim,
i've missed the opportunity to acquire all the PB chips i wanted during this time, but i'm still looking for something, if prices aren't gone too much high for the now more-than-common AC chips.
As i can see on eBay actually there are a lot of UK PB chips, and many AC roulettes. I guess this is caused by economy downswing, well, i'm ready to change your old plastic stuff for my fresh green bills
