I traded my XT50 for an XT70. Since the 50 was so great I really thought the 70 would be an upgrade. I just received the 70 and quickly took it to my test garden. I have been living and breathing all I could on the 70 over the last week and knew it quite well even before I got it. I also had a 30 a couple of years ago. Anyway I ran the 70 through all it's features and setting and hit my coin garden. All I can say is WOW! This thing does it all! When they say this is the flagship they mean it. Special thanks to Chuck at Indian Nations on such a great deal and fast shipping. He answered every email. I'm talking at least a dozen emails. I know he will take care of me. For anyone wondering if the 70 is worth the upgrade from the 50 - I can say you bet.
