We are looking into purchasing a new wet edger machine. Now it pretty much come down to HPE 410 and HPE 910 from CoBurn. Not sure if the price difference is justified? How's everyone's experience? Is it bad to use a HPE410 in 2024? We cut about 12 pairs a day. Speed is not that concerning. Although drill function is a good add-on for sure. Also would getting older machine means less convenient in tech support down the line? Thanks in advance.
