For automated benders, Accubend sales an okay entry level machine for basic block letters without difficult font styles but I have heard of many customer complaints with the management and customer support. CLN is better and have a pretty good bender especially for doing large radius letters. SDS Automation has by far the best benders and customer support. Their name used to be AdamsTech. The benders are capable of doing very precise bends and difficult letter styles. The software is more complicated as well as the machine so some might find them a little too complex. I wholesale trimless channel letters bent on an SDS bender. I also have UL certification. Let me know if I can be of assistance with channel letter fabrication advice or of course if you want to have me make letters for you.
There are many good routers out there. 70% of sign companies I've been to have Multicams. Just to qualify myself I've spent at least a week at Yesco, Allen Industries, AGI, Colite, Direct Sign Wholesale, and the list goes on and on. If you have any more questions about channel letters don't hesitate to ask because that is my area of expertise.
