Tony layne
Search on Facebook for a man named Tony Layne, he has a dwindling supply of Dymondwood and makes jump break cues, he can't guarantee a specific colour scheme and his prices will only go but his JBs are considered on par with Alex Brick's. Also his cues will likely be on back order.
Another option is Jumping Jax, I can't recall what the man's name is but he makes jump cues out of Dymondwood and his cue is called a jumping jax so that's another option although he will not make a jump/break, only a jump cue.
Good luck
