With 4K I could buy 8 cues that play well and still have ice cream money.
Monster Players, Hits A Ton, Real Stunner cues are always for sale. (Cough)
If you want a museum piece that supposedly plays well, have one built, and play Russian Roulette.
As far as resale, there are many cues people can't give away.
Find a cue to hit with before purchasing. The SBE is a good start, spend wisely.
If you don't know the type of hit you like, figure it out. You can put a quality shaft and tip on a tree branch and have a good hitter. A pig in a tuxedo is still a pig.
I have hit with some of the most beautiful pieces of crap on the planet. We call them casket cues, they look pretty laying on the table but have no life, they play dead, a dead hit.
I don't care if I'm involved in the design, or flew myself to brazil for a chunk of Rosewood.
If I can't play with it I am not buying it, the price is irrelevant.
