Did you try a proper brewing technique? Nespresso tastes bad in comparison afterwards. Under a 1000$ you can get decent espresso makers, too.
Each can make very good coffee and none of them taste bad in comparison to any others.
But if your budget is $1000, I would avoid the espresso category because you also need a grinder and a great grinder is probably more than a budget espresso machine and more important for consistent and good shots.
