Seeds Obsession Starting

I'm starting to get some catalogs of seeds and I'm starting to plan out what I want to put in the garden this year.  The variety is great but also makes for hard decisions.  I'm trying also to figure out how much I want to start from seed, and also what set up I might use for the indoor seed starting.  I'm also trying to be super-cheap about this, as I spent quite a bit last year on the raised gardens.
