I don't know that idiocy has anything to do with anything. People choose different engines for different reasons.
Is money tight, but you're willing to work? The old happy time may be for you.
Is function everything, looks meaningless and money less of an issue? There are quality rack mounts.
Like function, but looks mean a lot and money not a problem? Whizzer, my friends.
There are other choices in between and all around these.
Let's face it- many people who can afford $200 cannot afford $400, $500 or more. Further, it is not necessarily a matter of what you can afford, but what you choose to allocate to this hobby. Frankly, I can afford a new V-Rod, but I bought some property to build a house instead and spent less on my 2 wheeled hobby.
There's nothing wrong with choosing not to spend more. To criticize those who can only afford one option (or choose the lower priced option) or those who can afford more goes against the MBc ethos. We are here to help each other in whatever situation we find our fellow MBers in; not to run people down for making all the same choices we did.
