mate thats exactly what i had put in my previous post, that it would be expensive to pay some one to do it, so you might as well have a go and if all else fails then go out and buy a new one for 40-50 instead of spending 90 on a second hand set up, if i was you i would stop having a go at people trying to help you out as they will stop and you'll be left on your own wondering why nobody wants to help you anymore. as for "can the average joe do it" comment the answer is maybe, it would depend on your background with bike, tools and experience, i would probably say in your case no, but you might get lucky and learn something while doing it, all it takes is a spoke spanner, lots of time and patience and a ruler to see if its square on the bike once finished, its too difficult trying to explain how to do it and since you have blasted me before i really dont feel inclined to spend my time telling you how.
end of rant
