Many thanks for the info Don...makes my mind rest easy (grin)...I do like the

wasn't just superb.
I don't have a KX3 yet...ordered a kit on 18 Feb and still waiting (sigh).
And so the wait goes on...can't believe they are still shipping based on orders
received circa 28 Dec.....hope the backlog diminishes rapidly...I'd like to be
able to take my KX3 to the park before the weather turns cold (grin).
