Electric Fan Suggestions.

Ive been thinking about switching out my non clutch flex fan for an electric one, this is mostly a daily driver and probably wont see the strip anytime soon. so i dont need any heavy duty 3000cfm fans i dont think, but i dont know exactly what to look for, i saw one on ebay http://cgi.ebay.com/ebaymotors/NEW-16-Electric-Thermo-Fan-Chevy-Ford-Mopar-Radiator-_W0QQcmdZViewItemQQhashZitem4ceeabdc64QQitemZ330421754980QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories#ht_4728wt_951

but i dont know if it is any good, any suggestions on what type of electrical fan?
