Recalling a Beatles tune with a refrain of "Baby you can drive my car." No car, but a driver and that's a start. I have a concept but no Mark V...yet. It's on my wish list, and if I recall Alex does have one. Just a Celestaire practice bubble and a boy with a dream.... Nonetheless, the principles are the same. IE and bubble/SIC error before any other directed play. Thanks again for the tip on the Uniden 250. Lots of folks out of stock then. Recently found one through Amazon for $70 ($90 MSRP) with free shipping. Everything I need included (without the usual costly "ups & extras" accessory list). 120V AC charger, 12V DC charger, belt clip, wrist lanyard, and cradle. I went with the white/gray 250G unit instead of the "serious gear" black model. Less heating in the sun and easier to find in a nigh time emergency. Bill B
