Espresso Machine recommendations for a small shop in the USA

[stbobo]

Just opening up so I cannot afford the flagships (yet). I am looking for an affordable, reliable machine that has parts readily available parts.

I have found a few for sale on Facebook Marketplace, but when I try to find replacement parts, it seems that they are more available in other countries and this would be an issue for me. I am not afraid of breaking one down and cleaning it up, but I want to make sure I can replace anything that needs to be.

What's your budget?

I hope to find a used machine for less than $5000, but don't know if that is reasonable. I am fairly comfortable with repair and maintenance, although I have no experience with espresso machines in particular so I don't mind putting in a bit of work to get a good machine.
