I happened to walk by the clearance aisle at Target last year and there was a Logitech gamepad for like ten or fifteen bucks. I'd been considering getting a wireless adapter or a wired 360 controller to play Ys Origins, and wound up impulse-buying it. It was an easy plug'n'play (or if it was more complicated than that, I don't recall), and worked fine for my purposes. I didn't actually know what model it was or whatever, but flipping it around to take a look just now, it is the F310 mentioned in the OP.
I haven't used it all that much, just for Ys, Dark Souls, Skullgirls, and Chronicles of Mystara, but it's worked fine for all of those. It's also taken (more than) a few tumbles and still works just fine so it's reasonably durable. I really like that it's kind of a median between a PS2 and a 360 controller in terms of size; the Dualshock always felt small and awkward to me, and the X-Box controller always felt just a little clunky. My only concern is the D-pad, if that's important to you. There seems to be a lot of love lost for the 360's D-pad, and it's got a similar wobbly design; it is positioned and constructed a bit better, but still wouldn't be my first choice for a D-pad.
I certainly feel I got my money's worth, though if I had to buy it at the price listed on the Logitech website ($25), I might have sprung for something else (more than likely because it'd be dual-use). I guess it also might be worth checking the electronics section at your local Target/Wal-Mart type place next time you're there; I think I've seen marked-down gamepads there since then as well.
