Thanks Jadeski, I do like the idea of all the smoke it produces, but at $8.00 a refill for the oil, it could get expensive. Another generator I was looking at was MACK products 7090-ST ( [link]http://www.mackproductsrc.com/7090st_smoke.htm[/link] ). It's more expensive, but the smoke oil is just over $3.00 at Tower Hobbies. Problem is, I do'nt know how well the Mack unit works. Do you or anyone else know anything about the 7090 ?
