Please ask around before you buy anything off-brand. There's a reason certain brands are well recognized, it doesn't mean that all of them are worth the money they charge, but there's also a reason that off-brand machines are inexpensive.
If you can find an espresso tech in your area they may be able to help you find a used machine in good condition, or help you fix one up. They may also be a good resource on how different types of machines hold up (i.e. the Dalla Corte).
We've done both. We have a new machine and one we bought from a bank that repossessed it. We got an absolutely stunning deal on the latter. However, we also have a connection with a certified tech to rebuild and could afford, because of the deal, to do what was necessary to make the machine right. Didn't really need much as it had not seen a high number of cycles.
The used machine is now the centerpiece in our cafe and we can do catering where 220 power is available with the other machine.
The key is having a certified espresso machine tech available who can quickly get the parts you need and, if you can't, repair your machine. Down time is lost money. In fact, it's good to have a tech who has a machine in reserve for clients, like getting a loaner car from your dealer.
