I spoke with Gene on the phone, a few months back and asked him about pre-orders and his explanation to me, made perfect sense.
I do not want to speak for Gene but when going at a project like his alone, taking pre-orders can sometimes be a mistake.
Examples are all over this forum that show pro's and con's of the pre-order world.
If Gene did take pre-orders imagine how long the list would be members who would order his product. Then think about that one time when he would have to send out an email stating something was back ordered
Gene's name would get tossed into the mud quickly by people that do not understand he is a one man operation and that he can not just run over to the factory and pick up new parts. He has to wait for his mail just like the rest of us and some of the items I'm sure come from overseas and we all know that sometimes things happen.
I think Gene has a pretty effective system, he makes a certain number of drop-ins and then sends an email out to all the people that signed up for his newsletter/updates and who ever gets there first gets one.
It keeps everyone on an equal playing field and allows Gene to put quality time into making his drop-ins as opposed to just throwing a hundered of them toghter and hoping the all will have the same quality we have come to expect from Gene's work.
Give Gene a call sometime he is a pleasure to speak with and he can put things in perspective better for anyone wondering why he doesn't take Pre-orders.
