I have a 40 watt Epilog Legend.
It engraves up to about 1/8" deep and cuts up to about 1/8" plywood and 1/4" pine.
I haven't used it for six months or so, due to health issues, but when I did, I made some really nice signs by engraving the background and cutting out letters to glue in the engraved part. I also used it to make balsa R/C airplane parts and ply/pine model boat parts.
Also, it etches glass, granite and ceramic tile, making some really nice pictures and signs.
I have also cut paper, cardboard, leather and cloth.
It is a really versatile machine with almost unlimited possibilities. My wife calls it the "Magic Machine".
