A cheap Master deadbolt from your local home depot would probably be a good lock to start with.
Play around with it and if it's still giving you fits, search the site and find out how to disassemble a deadbolt and take out a few pin stacks (see link below)...
viewtopic.php?f=3&t=10677This is the best way to start, in my opinion.
You'll be fine with a standard US size pick kit to start with, but you'll probably want to add some slimlines to your tool pouch eventually. You can buy the slimlines you want individually.
