Usually, if people can spend $150, they can spend $300. It's not that much of a difference (and plain dumb to think that would serve as a basis for "snobbery").
That's pretty arrogant. I simply don't see how you have much knowledge of other people's pocketbooks.
Probably pretty ignorant, too. Take a look at your income. Then take a look at income distribution in your state. Where do you fit in relation to the median? There are lots of people for whom a $300 bike is out of reach, much less $300 for a bike computer.
There are certainly problems with IGPSport products, especially in terms of documentation and troubleshooting, but the cost of the products is compelling.
