Energizer TTL ENF-600N Power Zoom Flash- INPUT NEEDED!

[Wfpinky]

I'm still fairly new to photography (still have tons to learn), but I've decided I'm up for the challenge of learning to use a flash. I got some decent suggestions from a few people on here and today I stopped by the local photography shop to talk to one of the guys there. After telling him what I was looking at on Adorama he suggested the Energizer Power Zoom TTL ENF-600N. Looks like a great one that I can use for a while, but as I said I'm still a noob so I'd love input from people who have more experience. Price is around $120-$130. The Nikon compatible is on back-order at the moment, he said he's sells a lot of them, but he put me on the list for one and said he's got a new shipment coming in about two weeks. What do you guys think?
