Your budget would cover every reviewed espresso machine on this site except the La Marzocco GS/3. Have you read some of the
reviews? Given your budget, I would pick the Elektra Semiautomatica and the Mazzer Super Jolly, but it's a particular choice that not everyone would appreciate.
Other pairings for your consideration in no particular order:
Choice 1:
La Spaziale Vivaldi II
Cimbali Max Hybrid
Choice 2:
Vibiemme Domobar Super (or Quickmill Vetrano if plumbed-in)
Mazzer Super Jolly
Choice 3:
Elektra Semiautomatica
Compak K10 WBC
Choice 4:
Ponte Vecchio Lusso
Le'Lit PL54 (small footprint) or Mazzer Mini
