Unsolicited advice:
Pool cues are a funny thing. The feel of weight can be distorted by balance. A minor difference in the taper of the shaft can make a world of difference. If at all possible, try or at least handle a cue before buying. The last time I bought a used cue, it was at a pool hall. Lots of pool halls have used cues bought by management when the seller needed quick cash.
FWIW,
