Agree with Darryl. Replacing with used 003 would likely be the cheapest and most painless move. Any system that works well with 002 should be a shoe-in to seamlessly move to 003 with no fuss(other than maybe a driver update)
If you are running PT9 or newer, you have boatloads of options, but most will require the use of that company's monitoring/routing software, so 003 eliminates that learning curve. Got a dead mint 003 controller and would ship at USPS Global rate, but I'm not the least bit offended if you go another route
