ISO Men's cardigan pattern

I want to make my dad a sweater for his birthday but my mom says he prefers cardigans. I found this one http://www.knitting-crochet.com/meniricar.html but I have been all over the internet and haven’t seen anything else that I like. My dad is 59 and conservative when he dresses.

Does anyone else have any patterns for me to look at or books I should check out? And I have looked at the Knitting Pattern directory.

Thanks!

Maybe pick something from here??
