My tip.....be sure to answer all questions promptly!!
I have been battling to get any answer back from Machine Tool Camp on their machine. I have the 4 x 4 plan and it looks great. The engineering book is very clear and seems very well presented. However, I had a few questions before ordering some components from them (a good idea for a plan selling business...value added components) but they have left 3 emails unanswered over a week period. Their fax number as listed on the letterhead is not active anymore...... At this point I am not sure they are even in business.
Be available to answer question.
