I have been using SixBit since it was released after eBayBlackthorne became unsupported and at first we were a bit iffy on switching but seemed to be the best option.....SOOOOOOOOOOO glad we did. The program is great and if there are any issues the staff both through tickets and on the phone are great and supportive in figuring things out. We give a big shout out to the guys and gals at Sixbit and we are looking forward to many more years of working with them!!! You won't be sorry!!
