Just to wade in on these comments.
I had a very good relationship with my DTP, but I had a long term itch for something with an E61 group, hence the DTP sale.
No problems with switching from brew to steam, by the time you popped the jug under the wand it was ready.
I really had no valid reason to upgrade apart from the usual shinyitis/upgradius disease.
I have just bought the Mignon Specialita (I need to find a cure for this shinyitis/upgradius disease) which I am enjoying immensely, hence the Sage Smart Grinder Pro in sales.
