I'm with you Peter, I think Premium is the way to go. Don't get caught up in the hype until the machine is a known quantity i.e. is it going to be a good game to play as well as being 'Kiss' and looking pretty darn good. Looks like all the backglasses/translites are going to be the same artwork so in the grand scheme of things, there is really very little difference between a premium and LE machine by the looks of it.
There will be plenty of Pro and premium machines around for a long time I reckon to buy a NIB machine. I am hoping my business does well enough over summer to buy myself a premium.
