I was in a similar situation late in 2008 where I was trying to choose between the La Cimbali Junior S (tanked) and the Rancilio Epoca (tanked) machines.
Unfortunately when I approached the Rancilio dealer in Brisbane he didnt have any Epoca available for me to check out at the time.
In the end, a mate of mine ended up getting a La Cimbali Junior S (tanked). He was so impressed with it that I ended up buying one as well after having a play around on his. The Junior S was a big step up from the $300 Delonghi 330S manual machine that I had been using for the 2 years prior to puchasing the Junior.
In the end the build quality of the La Cimbali Junior won me over and its reputation for lasting 20 years plus. My Junior S has the vibratory pump whereas I see that you want to buy the rotary pump versions.
I have just recently bought a fitted Pullman tamper and ridgeless basket for my Junior S and that has improved the consistency and quality of my shots considerably.
All I can say is that Im extremely happy with the La Cimbali Junior S and I am making espressos better than nearly all the cafes I have tried in Brisbane.
Best of luck.
