I purchased my first RD from Roy, man I guess its been 5 or 6 years ago as best I can remember, hell it may have been longer. I bought the 8500 X-50 blue when it was the RD to have. I still have it and works fine at least as far as I can tell. Looking at upgrading it to a Redline if I can justify the benefits to the extra money a Redline will cost. The technology, laws, and weapons in this game we play sure have changed a lot. I did the hold three button down and power up test, it says I have revision 10, I think that's 1.0 right???? Maybe I do need to spend the money with a 1.0??? Will post lots of questions and do lot and lots of reading and research here.
