Love my Andy Gilbert, if you're looking to spend that kind of money and want a jump/break then I would highly recommend it.
If I wasn't going with that, an Alex Brick would be high on my list for a jump/break.
Don't really love any other jump/breaks and I would probably just get a cheap J&J if the above are out of the price range.
I still use my Jacoby jump cue though as it does jump better for short quick jumps. So I would consider a straight break cue like an OB or Predator if I was doing it again.
