I sympathise with tvcollector! Back when I lived I Florida I could not find hide nor hair of any tube color set(though I did get two monochrome ones), and I was not able to find one till I moved back to the midwest(then two rectangulars and two roundys came into my possesion).
I'd guess that folks in florida did not (for the most part) have the kind of money to buy color sets.
