Welcome to the forums! Its great to see another poster as well as a goalie!
The Nemmy is a great head. Many goalies use it. All the heads you mentioned are really popular. There are a few differences which may effect which one you choose. The Nemmy is stiffer, heavier, and offset. The Eclipse is much more lighter, has a slightly larger surface and is onset. The Eraser is the newest one and I have not had the opprotunity to try it out. But from the things I have heard, it is really good and measures up to the Eclipse.
I have used the Kryptolyte and I loved it. It was really light and had a good feel to it. Many people use the DB803. It is sturdy and light. I would go for the DB803 just because it is cheaper and works well for many people.
Good choice on the Super Freaks. They are a very trusted glove. Will you be getting the goalie version or the field version?
I have a Warrior CP and I love it.
This is the one I use. It is really light and flexible. It does not get snagged while making saves. The only problem that I see with the Warrior one you mentioned is the shoulder guards. I know they can get in the way while making saves. The Eraser is a great CP. I would definitely get one if I was in the market for one.
Good luck on your selections and good luck on your first year as a goalie! Keep us updated.
