Hello I have been reading your many and various postings and understand that you know most of what there is to know about ML-land. I have been using Ascents for some years, but now the upgrade bug is eating me. The chance has come my way to buy dealer demos of the Summit, though for roughly the same price - here is Switzerland - I can but a new Spire (the price differential between the USA and Europe on all items of this class is simply staggering - so it goes). Would it be too much to ask you to attempt an answer to the following: how different are the Ascent and, say, Spire (for that matter, the Summit)? Not to put too fine a point on the questions, are we talking about a night and day difference? Thanks in advance for your consideration
