Energon comics. Yay or nay?

I was at my local comic store earlier, and I spotted the entire DreamWave Energon series under the Transformers section. The bundle cost $40, and they were all in pristine shape. I remember nothing of the story, other than it being a continuation of Armada and Galvatron killing Scorponok. I liked Armada (cartoon and comics), but I didn't care for the Energon cartoon series, as little as I saw of it. I did like Super Link, but the 2 were very different, I was told. Anyway, I was curious about the comics, but didn't feel like opening each issue from its sealed bag-and-board. Is the series a worthy follow-up to Armada, and are the 12 issues worth the $40? Also, I liked Simon Furman's writing from back then, but the ReGeneration series let me down big time. Did he still have his touch with Energon, or did he lose it by then?
