>>975530Frankly I've never liked any of the half-platform pedals that I've ridden or have had my hands on (mostly SPD variants or clones of the same), but if I had to buy any of the options currently on the market it'd be the Crank Bros Double Shot, the platform is actually wide enough and at the right height that they look like they'd work tolerably well.
>>975516That first Trek you linked to is a solid deal, I'd grab it immediately. Other two you linked to are too small. Other finds:
