With PTSC trading at $2.25, +500% from when my friend Roger first mentioned it to me, it may be worth looking at EDIG, which Roger mentioned this morning as an interesting speculation. It's trading at about 15 cents, has been much, much higher in years past($5.00 in October, 2000). They make a hand-held video product and have some association with PTSC management, the details of which I am just now looking into.
Here's a link to their web site.
Consider this an early heads-up.....I will look into the company further and report back.
