To address Lux's point, the Shark is a relatively inexpensive cue. The cost will add up for an extension, case, shipping, customized badge, additional tips, etc., but the total will still be reasonable.
If you select a cue for The Hit rather than for The Pretty, then for the cue and accessories shouldn't cost more than $300 to $500, all in. As it true for pool cues, spending additional money means you're paying for fancy splices, a cuemaker's reputation tax, wood from one of the last remaining planks of the Round Table of Camelot, or perhaps ivory accents made from Babar's tusks.
At any good U.S. pool hall there is a veritable forest of pool cues to try out. Not so with snooker cues, obviously, since finding even one snooker cue within a 100-mile radius of one's home can be difficult. If you head out to the U.S. national championship or Embassy Billiards in California you might be able to try several cues. Once you have your first snooker cue and play with it for a few years, choosing the specs for the second cue will still be an educated guess unless you're lucky enough to try before you buy.
No less a snooker giant than Joe Davis recommended finding one good cue that feels right and then using it for life. If your first cue is a good one, though perhaps not a fancy one, you may warm to it and not need to spend additional money on another. To that point, my dog barks too much, my car handles in the snow like a hovercraft, and I just introduced a wobble into my Shark after steaming out some nasty dings, but all this stuff is mine and I'm used to it. (I'm also sticking with my wife, even though she has no faults.)
Good luck! It's been fun to read your posts and see how you've been getting into snooker.
