I've hesitated to tackle afghans for precisely the same reason. (terror of the unending project + ADD = :hair: ) On my Amazon wishlist is the book
Big Needle Afghans
I checked it out at my library, and there are a LOT of really pretty patterns, using either big or doubled yarns, most of which are quite contemporary (I'm just not into the lacy granny square-looking thing, unless it's actually crochet, but even then...). Lots of cables!! It's pretty reasonable on Amazon too, haven't checked ebay yet.
I've downloaded the errata f/somewhere, I'd google and get 'em if you get the book!
