Before using Ruby/Rails, I've researched several financial quoting web-services. Some are free with limitations, others are not. For real-time quoting, it may be worth the money to buy such stuffs, but for delayed or historical quotes, I found Yahoo! Finance data downloading function is good enough. The csv file forma= t is very easy to phrase and import into database. The above mentioned Ruby/Finance library uses Yahoo!Finance as well. Hope it help.
