e36 radiator/fan ebay

[e30boarder]

i was looking on ebay for an e36 radiator fan for my e30 electric fan swap and i found a bunch of "race" radiator and slim fan setups. Are these any good or just cheap crap?

for example..

Im still leaning towards finding a decent fan at a you-pull-it lot. Thats a hell of a lot cheaper than one of these. Any input is appreciated.
Thanks
