palciatore@... not to sidetrack your discussion, or open a can of worms, but to call a QC gearbox "Extremely Limited" is silly. In addition to all but the rarest  English threads, you have the ability to instantly change your feed rate- something that is far more valuable. In addition, you can cut Metric threads very, very closely with but one gear change, and you can cut all of the same Metric threads as the Model C since you can also use the Metric Conversion gears on the Model A as well.  And  you can still instantly change feed rates with the Metric gears in place if you need to do a non- threading operation on a part.
