Sci-fi/fantasy magazines to submit stories?

I’m looking to submit stories to sci-fi/fantasy magazines. I realize most of everything is online now. It’s just been tedious (and a strain on the eyes) looking for good ones.

I submitted one to Fantasy and Science Fiction, but was rejected. I’m considered something for Asimov’s Science Fiction, and then I discovered Lightspeed. Then I just tend to stumble upon rather mediocre ones with crappy website set ups. . .

Along with other places to submit, any tips on what they like to accept would be helpful, as well as the overall word length they accept.
