I have been using a Flex 1500 for almost 5 years now BUT yesterday ordered a Flex 6300. I have been really excited about the 6000 series since I saw them announced but it took me a while to save the pennies for one. I am very excited about the programming API and the rig itself. I have been reading all the posts I can and look forward to setting the rig up with my SB-200 amp and my Elecraft XV144 transverter. I really really love my 1500 but I am totally stoked to get my 6300 and start playing with it! Thanks Flex Radio for bringing me all this FUN in my #1 hobby! And thanks to Matt who supplied excellent customer service for helping me with the order!
