which of these should i purchase for lighting

[Thaxist]

I definitely wouldn't get that Odyssea one, it is way overpriced.

I have the 48" 716W model, and I'm pretty happy with it but I only paid about $400

I'd suggest:
http://shop.aquatraders.com/Odyssea-...V2-p/54204.htm

Also, look at the Aquatrader's site. They don't have the greatest reputation but their price is awesome.

TopdogSellers from ebay has a lot of Odyssea stuff, and he has a pretty good reputation.

The Current USA fixture is a reputatable name and a good price. I don't know about the third one.
