Homebrew PCBs

Hello Dennis,

Yes, when there is more money in the bank, I think I
will buy that HP1020 lazerjet printer at Best Buy.
Together, with also buying inkjet transparancies at
Office Depot, I should be in business...as I already
have the iron!

Do send me your e-mail address, as I will keep it, and
then when the time comes for me to purchase
everything...I could very well gets some good tips
from you...if you like. I've been a 'dry transfer' man
for 3 years...well...change is a good thing.

a friend, Patrick
