I use BizFilings for a single-member (me) LLC incorporated in DE. I think it costs $200-400/year, mostly in DE fees. It's all Schedule C expenses, of course, against your income -- make sure keep good records.
If you're doing an LLC and not planning on any future investors, Delaware isn't really critical, IMHO. (Many investors want a C-corp in DE).
Finally, even though it's just "paperwork",I found having an LLC with a real EIN (and a phone number and FAX number and a real address), added some legitimacy that has been very useful in a few circumstances.
For example, health insurance for a one-man business (me) was cheaper for the same coverage than the "direct" plans for individuals. But they wanted a bunch of proof, like my certificate/articles of incorporation in DE. Go figure.
