Tesla Coil Capacitors - Why build them?

I see a lot of people asking a lot of questions on how to build their own tesla
coil capacitors and using large arrays of polyprop caps to build
MMCs (which i think can cost lots of money itself.)
 
I realize that half the fun is building your own . . . 
 
but, why not just buy new ones . . . its not very expensive.
 
I've purchased 30kv and 45kv (0.01uF through 0.05uF) capacitors from High
Energy for under $100.00 apiece - probably much cheaper than
building a large array MMC.
