I am about to start up a small laser engraving business here in Fiji. I've been intrigued with laser engraving for many years but never made the jump. Having read many posts here and being far from any hands-on support, I've decided to go with either Epilog or Universal (i.e., not Chinese) and my main question is what power to go for. I expect most of my business to be simple stuff (leather key fobs, awards and plaques, wooden name plates etc.) that (I think) can easily be done with 25-30 watt lasers but do not want to paint myself in a corner. Should I be thinking about more power so I can handle a wider range of materials?
