Welcome to CoffeeSnobs.
Uhhh--what was that budget again?
What sort of brew do you want to make?
Do you want to froth milk as well?
How many do you make at one time?
Where do you live?
Do you have grinder already, or does the budget include money for one?
These will be a good start.
Or you could cruise the site in the appropriate price categories.
Or you could use the search.
