Given the equipment you have, you should be able to get into an Amati Tradition or Serafino within your budget. They have essentially the same tonality - the latter better for somewhat smaller spaces. And, you might even be able to pick up a pair of good condition pre-owned Il Cremonese within your budget. What’s your room size?
If you really can’t audition them beforehand, I’d suggest you consider purchasing a pre-owned pair which you’d be able to sell for roughly what you purchased them for if you didn’t like them.
