Cool!What I'm trying to say is, if I buy all of the parts separately, it comes out to $250. Since I am buying from another re-seller they still need to make a profit out of me (and the manufacturer needs to make a profit out of the re-seller etc.). I assume from this that Pro-Lite must be making a fair bit from each wheel, especially if they can buy the parts in bulk at a lesser price. Compared to other companies I guess pro-lite's profit margin is lower, but their R,D and technology/marketing seem to be too.
I'll have a set for $250! Do you take credit card? Can it be on the courier today?
I'm assuming from your comments you won't need money for your time in building or selling them.
In all seriousness though, there are plenty of things that are heaps cheaper to do yourself, if you don't add a value for your time, the skills involved or the need to make a living from it.
