All I will add is if you get into the kitting end of it. Is do the best job you can and remember CUSTOMER SERVICE is going to make you or break you. I just recentley bought a kit from a company (Wll known one} that lazer cuts most of it's kits from others plans. The job of cutting was very, very good, top quailty wood and such. But my kit came shorted a few parts. I tried contacting this company via e-mail several times about the shorted and broken parts. Not once did the person in charge contact me about these issues. I then called this person and spoke with him. He said that he would send me the missing parts ( very good so far) but he also told me that there will always be some damaged parts in every kit ( Bull S#$T) and that I should just glu the broken parts back togeather.

This is not the best customer service I feel. And just this morning I get a e-mail from another person that said they had serious problems with this kit cutter as well.
My point is if you get into it. Then do it well and take care of your customer base. If you fail that aspect you will fail everywhere else.
