Best case for older (1st or 2nd gen) iPhone?

[atomheartmother]

What is the best case for a 1st or 2nd gen iPhone? I'm not sure which generation it is, but it's not a 3G. This is the model number: mb384ll.

Any recommendations? A lot of people seem to like the invisibleSHIELD, but it also seems to get a lot of bad reviews claiming that it's extremely difficult to put on.

Any recommendations? How is the Griffin iClear? I have one for my Touch and like it fine. I think this is the correct case for my model.

I would go with the incase slider. I used it for the first iPhone that came out and it really protected my phone. As for the invisible shield, some malls have stores/kiosks that will put them on for you.
