Fleshlights are great, and, as I just posted on a new thread, they've got another model that just came out with a squeezable case. I've used some fancy fake pussy/ass models including the Fuck Me Silly, but I've found em highly dissapointing (the FMS is the only one I've found that's 'meat' is properly firm, but the entrance itself is too loose and easily rips). I've used a few sleeves like the head honcho, but without a case like the fleshlight they're hard to hold (lube gets all over them and they slip out of your hands). The majority of the machine types are junky novelties (autoblow), though a heavy duty fucking machine for dildos can have a fleshlight attached (never used, but the concept sounds great). Suction is hard to reproduce in devices it seems; the venus2000 is the only one I've found (basically a mini cow milker but its like 800 bucks so screw that. Masturbating with pumps and the crappy sleeves they come with never did it for me (though get a big one and slip in a fleshlight sleeve for some great pleasure).
