Looking at upgrading my overpriced hobbyist Printa screenprinter for a serious commercial manual press. We are looking at Vastex, M&R, Hix or Antec Legend. We know we need a 6/6 and we need a bigger conveyor dryer. We also like the registration system Vastex has. Any suggestions on these brands for those of you that have used more than one would be very helpful. I know everyone is partial and bias to their brand, but when that is all you have used it's hard to make a fair rational opinion. Also, is it better to buy new and get the training and warranty or since we are already in the biz is buying used the best option? Thanks for your info.
