i can understand trying to save a few dollars here & there but... i think most consumers like for purchasing to be as easy as possible. give it to me in a package where i don't have to find dimensions or even THINK to get it right and its more apt to find buyers. 2nd, i think guys in the RC hobby kinda like stuff that's tried, true and pretty much guaranteed to give you the results you want cuz though money is valuable in a sense, so is TIME and EFFORT. what happens when you get ONE size wrong? what happens when the performance isn't the best? then you've wasted the money you thought you would be saving by going cheap when it would've been right the first time by going for something already known to be of high quality and to the EXACT specs required?
do your thing, enjoy the hobby... but really, going cheap isn't always the best answer and expensive doesn't mean 'bad'. besides, 'expensive' is a relative term
