That's a tough one...I really don't like Paragon and have been staying away from there, and they're probably too expensive even with sales. Emilio's in Queens might have good sales starting a little later into March and April, and you can probably call them to ask. Who knows, maybe they'll be ok with some haggling? They tend to be a little bit nicer than the guys at Paragon.
I'll see if there's a sport-specific recycling website for nyc, but for now I'd try yelp and craigslist. I managed to score a free pair of new boots for my sister last year...it just takes lots of reloading the page! (Perhaps not so worth it if he's supposed to be studying instead )
