i will try to make it simpler. no time to right a lessons learned for people that already have their optishot/protee/gsa sim and just want to read and critique it. any newbies (which i fall into that) doing research have and can always PM me with questions that went into my decision process. i am open and provide the good and the bad i have experienced. once i get time and come up for air then i can summarize for future reference.
