dependin on ur budget man. the cheapest price on 12" w7 i have seen is 500 bucks w/o shipping. if you can get it anywhere cheaper than this price, u are lucky. i said it depends on ur budget because those w7's are power hugry. u will need lots of juice to run just one w7 otherwise it won't push hard. but if you already had the amps you want in mind, it's easier to make up the rest to match with them.
