to expect $350 odd dollars for this application - it is extremely unstable and has caused many problems. I am running intel macs. I have found 'Mac Barcode Label' from OnlyMac software to be the best barcode application we have come across so far, - professional, very maclike interface (without the amateurish ugly buttons of bar code pro). Can remember how much we paid for it but it was nowhere near the price these people are asking and comes highly reccomended.
