I have the gaggia classis pro, just added the OPV mod and PID. It is pulling pretty good shot right now and quite satisfied. The problem with the breville is the build quality and 54mm portafilter. I was also about to get bambino plus but googling the longevity of it and i have some doubts above it.
If you import a silvia, you probably can get it at the same price of a bambino plus maybe even cheaper. Warranty tbh is overrated, get a good product with good reparability and you should be set for long term.
Silvia has a bigger boiler which means longer to heat up, the workflow is also much different. Normally you pull a shot then steam milk. But on the Silvia, people tends to steam milk first because of the size of the boiler it will be faster to cool down a steaming boiler then heating up.
Both Silvia and Gaggia doesnt have a PID so brew temperature will be off and you need to temp surfing.
Not sure why you say steam wand is not as good, i can steam milk just fine its just that i no skill to pour latte art. The steam pressure is not really that big of problem, you just start steaming before the steam light goes on and you can steam forever.
