A $4 beer will never get you 4x more intoxicated than a $1 beer.
A $400 watch will never give you 4x the performance of a $100 watch.
A $2000 pistol will never give you 4x the performance of a $500 pistol.
An $80,000 all stock car will never give you 4x the performance of a $20,000 all stock car.
Surely we've all heard at least one of these arguments before...
I haven't forgotten the OP's question.
The OP asked if Busse's are worth the money. He didn't ask about diminishing returns, the value of a dollar in 2001, or if the name of the company owner was Gary Busey.
The problem seems to be that many here have forgotten that this is a KNIFE forum. If we all got by satisfied with only the cheapest (or least expensive) edged tools, most of us probably wouldn't spend much time here because any old knife at the Home Depot, Lowes, WalMart, Sears, etc. would do until it broke, and then we'd just go get another. Or maybe we'd just go grab a kitchen knife and use it wherever... But really, where's the fun in that? Bladeforums didn't find us, we found it.
So... We gather here with a common interest. Knives and other edged tools... What's good enough for one person might not satisfy the next for whatever reason. One man's trash is another's treasure, and so on. I like what I have, and no it isn't all Busse(kin)... And I don't regret buying any one of them, custom, production, whatever. Ya don't like them, so be it. At least with a Busse, you have a considerably better than average chance of getting all or most of your money back selling it right away if you decide that the one you just bought doesn't suit you...but surely Jerry's knives aren't the only ones that can.
The real truth is that everything is relative. What's great for me may suck for you. What I can afford, perhaps you cannot or don't want.
I would think that much like this country's current (mostly) two party political system might be to those who dig politics, life would surely be more boring to those of us who really like knives if there were only two main knife companies and very few independent knifemakers.

Choices are good, yes?
