Just a short word or words of Praise! I really love my 6400, learning more every day I use it, like it so much talked and friend of mine into buying one, there is a little learning curve but if i can figure it out, not too bad. documentation not bad for the software but hardware could use a little tweaking, JMO! and the customer service has been great, nothing as far as it working, just cosmetic, handled it like a champ and easy to work with, all in all, VERY HAPPY!!, thanks again Flex!
