Best vender for rear drop?

[PaPaStewySnipes]

I'm looking to order a rear end package. 4" drop leafs, 1.5" shackle, new drop shocks front and back, relocators, new hardware and drum kit... Etc. Who has best prices. You guys say ece is great and I'm leaning that direction, do I purchase directly from them or possibly can I get a better deal elsewhere. Any reviews on cpp drop springs, I havent seen much about them most go ece. There might be some labor day sales coming up I am unaware of.
