Quoted from viperrwk:

Ed @ GPE used to sell a kit with 3 caps and the cable ties. I don't know why he discontinued it.
12000 mfd @ 25v: http://www.greatplainselectronics.com/Category-67.asp
150 uf @ 350v: http://www.greatplainselectronics.com/Category-108.asp
2.2uf @ 50v: http://www.greatplainselectronics.com/Category-108.asp
with four cable ties.
The price of those separately is $13.80 on Ed's site (though he's out of the 12K cap currently.)
I'd be surprised if you found a kit on ebay to do the same for $8.
