Which magazine is worth subscription (in paper)?

I've cut all my paper subscriptions (or digital, for that matter) except for these 3:

- Communications of the ACM -- the signal/noise ratio is good, and the value for the money of an ACM subscription is excellent [1]

- Circuit Cellar - good if you're interested in electronics, FPGA, DIY projects and similar stuff

- Maximum PC - I like keeping an eye on what's going on in terms of PC hardware, watercooling machines, etc.
