I am in the process of looking for a replacement laser for my aging ULS 25ER. It's been a super working machine for three years now but I know that time will eventually force me to buy a replacement. So, I am looking at all low cost possibles including the Chinese laser option. One thing that I noticed here is that few people mention what one of these used imported units is worth. There is a 60 W YH-G9060 unit locally for sale that was imported three years ago but never used. It needs to be wired for US 220 Volt connection and the fellow is asking $6000. It occurred to me that I have no way of evaluating what this unit is really worth. Will it even work after sitting idle for three years? What happens if someone buys it and it needs repair? What is the realistic lifetime of one of these older units? Are they obsolete faster than the more mainstream types like ULS and Epilog? Thoughts?
