No problem here at all, I fully appreciate your response and view point.
I get the boring thing and agree, I have owned over years gone by 4-5 different machines which were a novelty at first but as you suggest got boring after a while.
Saving in the cash box is part of the reason I am considering a real machine, Ideally (even though I mention Up n Over) with no "empty" that I have knowledge of, otherwise said cash box would always be empty and I'd spend more time with the refill key than playing
Thinking about it more, I may have to wait to move house also as I Struggled to find somewhere to put our Xmas tree this year
