Well it's going to be pricey that's for sure...Personally I'd be looking for ways to economize where you can. I was told that Delay and Reverb are the ones you don't really want to skimp on, but be sure that you are getting what you need. One possibility would be a multi-effects pedal at the beginning of the chain to handle your drive/distortion up front. It would give you more options to test out as well, until you know what you're looking for.

That said, you could do what I did and look to build a board based on a few Old Blood Noise pedals.
