Homebrew PCBs

The price is very competitive, although the disavantage is that you 
must buy a roll. I believe that this company makes a great service of 
selling that medium size rolls, since the original roll from DuPont is 
only available at 400 ft. and it only sells in a B2B service, not even 
to individuals or homebrew makers.

Does anybody has purchased from thinktink in the past soldermask or 
photoresist and laminate their own boards? If so, could you explain 
your experiences?
