I am looking into getting a rotary engraver, a simple one that will do glass of many shapes and sizes. I find Roland brand engravers will do what I need, without the $15,000 price tag! I am a single (widowed) mom of a now 11 year old boy, whom I would like to send to college. I am 52 so my time here is becoming more limited and I have to get on the ball! I currently do personalized "etchings" on glass mugs with a chemical medium. I find this is detrimental to the nasal passages and who knows what damage it is causing :( With this machine I can also create other items that I currently cannot so I can expand my offerings. I thought if enough kind people would donate a dollar or two to my cause, I could get this engraver and get more done, and in a safer manner. Any help toward my cause is GREATLY appreciated.
