all: agreed! I have been using these things for a few months now (qt110 and qt112 mostly), and they are indeed fantastic! Easy and effective and cheap. I found out about them through postings on the basic stamp list. I am so fond of them that if anyone has any questions to post i will do my best to answer them! -raphael -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
