Welcome to CS Brendon.
Very simple reply only reqiured, by answering a question with a question.
Do you want a good, functioning, new, no fuss coffee machine straight up so that you can enjoy the coffee now, or are you looking for a project / hobby with coffee some time down the line or never?
If you want a good functioning coffee machine now there are several in the $2000.00 range that do an admirable job. These ARE micro sized commercial machines not large domestic machines, & are called in the industry "semi-commercial".
When comparing these to larger sized commercials, there is not necessarily any detectable diff in the quality of performance (given certain variables that its not necessary to go into here and now)* except where the larger machines can produce more volume.
Also new machines have been developed, refined. Old machines that you do up are just old machines that you did up.
As you are at home and not in a small business or cafe, the volume doesnt come into it.
If you want to look at some great, new semi commercials, we import and sell BFC Junior machines and highly recommend them.
You will also need a good grinder to match to the machine without which, any good coffee machine is not going to do it for you ie pre ground coffee or coffee ground with small / cheap end grinders will not be suitable to the task, think of it being the same as hi fi. Good amp but cheap turntable or CD player simply = good amplification of garbage sound.
I hope that answers the question.
