Need help to choose a cheap greenie.

I'm pretty new to lasers, and I need help to choose a first, cheap green laser. About $20 preferably.
I'm most interested in performance and divergence, as I want it to have as much range as possible. It's also a plus if it uses CR2 batteries, and that it lasts a while.

I've been looking at:
dealextreme.com/details.dx/sku.12274 and dealextreme.com/details.dx/sku.7883

Which is best? Are there other similar lasers?

Sku12274 is focusable by unscrewing the head and turning the lens which can all be done be hand but uses a CR123A.

Sku7883 i would go for this http://www.kaidomain.com/ProductDetails.aspx?ProductId=1246 a member and one and it measured 76mW'ish.
