Actual price difference? No. Everything I've read tells me that APDN is more expensive because its the better solution. But I think we're talking nickels versus dimes here because if APDN was dollars or tens of dollars, there wouldn't be an incentive for colorcon to use them both.
Funny thing is the Kelly Boyer's quote in both COLORCON PRs (trutag and APDN) are almost identical even though they are a couple of months apart. Big difference is in how colorcon describes each relationship. For trutag, it's a development agreement. For APDN it's a commercial agreement.
Looks like APDN has a 2/3 year head start on trutag.
