Prices vary wildly. IEEE starts at $5695 per 350 downloads per year [1]. ACM membership + library access is a very reasonable $200 [2]. I can't find an all-access subscription for Springer but individual journals range from 100 EUR to 20000 EUR per year [3]. JSTOR only sells subscriptions to academic institutes and libraries [4] but you can buy 14 days access to a single article for $10+ [5].

Just to clarify, individual IEEE membership is much less expensive. Full membership in the U.S. is $181/year and includes online access to all IEEE articles, dues for other parts of the world are even lower (for whatever reasons) [1]. For students it's $32/year.

I may be wrong, but I don't believe that membership provides journal access. It's not mentioned in the membership benefits and there are separate prices listed below for individual societies.

I apologize, you are right. I misinterpreted the information given on the membership benefits page (about the IEEE Member Digital Library).

Apparently membership to individual societies (add $9-$53/year, depending on the society) may give you access to several journals via IEEEXplore (IEEE Trans. Image Proc.; Audio Speech Lang. Proc., etc. for Signal Processing Society).

As I can't find a reliable source to quote (their page is a mess), I can only speak for myself. I became a student member because of the ridiculously high conference fees they charge, which are heavily reduced if you are a member and/or student (Conference pricing deserves a rant of its own. But I digress.).
