Have you tried Misumi? The only problem I had was
that you have to be
VAT
registered. I had a friend order for me.

I used the 150 mm / 6mm variety and as far as I can tell it works
nicely. I
have been running a tape in a Tektronix 4051 for some time and haven
seen
any shedding. Not daily exactly but 20 times over half a year.
I second the Misumi brand. I haven't seen any of the issues mentioned on this thread
with those bands. Of course I am only a hobbyist so not putting them through any crazy
paces. I mainly use them for the 5100 and 5110. They are significantly more expensive then
the Amazon mix bag ones but may be worth it.
