Nah being a sad git I actually would get quite alot of enjoyment out of building my own.
Having everything how I want it, not how some designer has made a compromise between what the market will pay and what he could really do.
I will grant you there would be some blood spilled but it would be my own.
Tears never, swearing frequently I grant you especially when dropping screws.
Sweat only when my head gets to near to the lamp I will be using.
If you have the time and the inclanation why not?
Mind I am one of these types who is going to build his own aircraft eventually.
