3g modems in finland? Any plans for a month or one week?

Dear Lazy web,

Are there any 3G usb modem plans available in Finland that I can get for one week or a month? I'd need to buy the modem too.

Hopefully it should work two hours drive from Oulu.


Update: used a modem by Elisa. Worked well, even 3g. Closing comments because this post is getting spams every day - and blogger.com spam protection seems broken.
