I'm using pasar malam ones, one of them crack probably of heavy usage but never scatches the iPad... do not see much different of usage between a 30 and 300 dollars plastic.

I do not need a 300 plastic when a 30 plastic can do 99% of what I need! IMO.

I like lifetime warranty for some products, I take care of my gadgets so lifetime warranty for a piece of iPad plastic cover is overrated for me, YMMV.

Having this thread here is really helpful for me to find a suitable and not expensive case, thank you.
