i actually ended up going with
radiator.com. i was considered getting a koyo from
absoluteradiator.com for $155 + shipping, but 1. i've never seen a koyo for that cheap, 2. don't know if "absolute" is trustworthy, and 3. i want the radiator for this weekend.
anyway, i called radiator.com. they didn't have the bottom of the barrel ($100) CSF radiator in stock at my local warehouse, so i got a samsung (heh) oem style from about $118 after taxes. drove up during my lunch break, and picked it up. looks good so far.
now i have to pick up antifreeze and a new thermostat, and i'll be good to go.
