I couldn't be without my Brother label printer, the only disadvantage is the price of the tape but you can find good deals on eBay. I had a 1230PC before I upgraded and they are very good and like Stephen says are available cheaply.
This is really nice stuff:

I have TEKU rigid black square pots available in 9cm and 15cm sizes.

Will also have 13cm pots in a few weeks.
Kind Regards,
