1. rotary pump
2. dual boiler
3. E61 Brew group
4. Plumb in capability
Does such a machine exist for under $4000?
Thanks

Buying a machine based on specs, such as you give above, is like having an operation from a surgeon who operates on you with a surgical textbook next to the OR table, just in case.
Based on what you have posted in this thread it is my opinion that you do not know enough about what you are searching for to be able to even tell the difference in the product produced by any number of fine machines that out there and which do not meet your specs. I would throw the GS3 into that mix as well, as a machine meeting your specs which will not produce "better" shots than any number of the others being operated by experienced home baristas.
Espresso is more than a recipe for a certain type of coffee produced by a certain type of machine. It is a culinary product with a particular recipe that varies depending on what you are trying to make and with what sorts of coffee and what sorts of equipment. There is not one definition of "good" and "better," but many.
In making excellent espresso, one has to have a certain level of equipment, which includes a very good grinder and a good espresso machine. With this level of equipment, the most important other factors are (without question#1, the most important being) the COFFEE ITSELF, and following that, the person making the espresso drink. Somewhere much lower on the list is to be found the differences between what you would get from a lower priced E61 machine vs. something like a GS3, by competent operators.
I have left out of this discussion basic competence as a barista. This is important however if you use Italian-ish type dosing, e.g. ~12-15 g for a double basket, assuming proper grind, the espresso shots more or less make themselves.
If you really want to make the best espresso available, concentrate first on the coffee that you are using, next on the grinder, and only after that would the espresso machine come up, and then it would be less important.
HUGE improvements in espresso quality come from the COFFEE, way before they come from anything else.
