Hehe, thanks :)...and about wondering for the rest of my life - ain't that the truth! I keep eyeing up my remaining T01s, but I'm loathe to waste them. :bigsmile:
@SantaKlaus - I was lucky enough to find two 5-packs a little while ago - couple of months?, I'm guessing old stock. They were (are, I still have some left!) Maxell branded.
Edit: found them in a store here in the UK called Curry's (or, as I have been reminded, Currys.digital as they're now called).
