The main reasons for the Lusso would be temperature control during sessions when you pull multiple shots, bigger boiler capacity for the same reason, different footprint which is heavier and more stable (although the Export is quite stable compared with a Pavoni), boiler pressure gauge, larger drip tray and cup warmer, can be left on (but takes longer to heat up). For me, I very seldom use any of these features, but that does not mean I would not like the luxury of having a machine on a ready all the time. If I knew I had the space and would not need to move it around much I might prefer the Lusso, although I might want to de-brain it a bit.
GB, thanks for the post. I've been meaning to order those temp. strips. I know you did some group temperature tests a while ago. If you watch the temp strips how does the group heat over the long term, both when sitting idle on, and during and after pulling a shot. I suppose that pulling the shot heats the group considerably, but I would be interested to see how fast it cools afterward.
Where did you get the boiler-cap pressure gauge, and did you see any rust when you replaced the bolts? Probably time for me to do it as well. Plus, my piston seals have not been lubed for over two years (although they appear to be working very well - I'm not sure how often they really require lubing in fact).
I can't recall any major difference in heating with the 220 element, except that it was, and still is, quieter. I seem to remember the 110 element making little noises.
My mater p-stat is five years old and still appears to be working well. I guess it drifts occasionally, and I need to adjust it a little.
One important consideration is the the Export pstat is on the bottom of the boiler, so particulates will accumulate there. Once I figured this out I began to take the precaution of completely emptying the boiler each morning, and before doing so, I turn it upside down a few times to dislodge any particles that might be sitting in the pstat.
