It's not how I feel -- It's just simple economics. If the X-Breaker cost less than $350, more people would buy it. Conversely...Fury, Sledgehammer, and Predator would all sell fewer break cues if they raised their prices.
Like someone else said, there is so much competition these days with jump/break cues which perform extremely well. When you find something that works well for you, there isn't a lot of motivation to buy another product which costs more money even if you know the product is a little better.
Think about Sony Betamax versus VHS. Betamax had a clearer picture and sound (especially with the Hifi add-on option) but it cost more money. Most people considered VHS more than adequate, and VHS sold so well that Betamax went out of business. Sony probably didn't understand why people would choose the format with inferior picture and sound, but it was economics. Later, Super VHS came about to fill the niche for people who did demand a better format.
In this case, it's even more difficult to justify spending the money because it isn't obvious whether or not the X-Breaker is superior. It may or may not be -- but it's a new product which has not been bought (and heavily reviewed) by several members here. Maybe over the next few months some better reviews will be posted, and maybe I'll decide it's worth it.
Hey, no friendly discount for the locals? In fact, an additional shipping charge and 14% tax? Boo... hiss!
