You should check expedia.com or similar for a cheap one-way fare TLL-HEL if you don't want to take the slower (but in some sense much nicer) boat option. Last time I flew one I got it for 50 EUR all-in. Just don't try to book it from Finnair's website as the stupid POS rules and obscene service charges make it much more expensive.
It gives you a few meager miles as well.
