"I cannot buy the Excalibur because the government does not allow it." Stupid question: Why?
I've seen really nice Japanese scroll saws that auto clamp the blade under the table. Super quick to change blades or put it through another hole. The profession level saws that have an arm mounted drill seem like something a person making a living with it would want.
I'm not so sure about your government not allowing the saw (that seems a little odd to me) but either way, you wouldn't be able to get one if you tried unless you purchased it second hand due to the fact that they are no longer in production. The rights and design of these saws has been sold to King tools and they are now manufacturing the saw under the name of Excelsior. They are manufacturing the saw with the same specifications as the Excalibur but I have been speaking to my General International Rep and he couldn't confirm the quality control of these units. I do know of one person that owns one and thus far (about a year now) he has been happy with it.
