I have the iloome ScreenMate Flex Flexible Glass 8H and paired it with a Ultra Hybrid by Spigen. The screen protector is great. It reaches to the edge of my iPhone. You can't really tell if there is one on my phone. I had several people tell me that I need to get a better case because I might crack my screen. They are shocked to find that I have a screen protector on. Total cost for both was around $26.
If you like something that is slim, their Slim Armor S is pretty thin but still packs a lot of protection.
I'm liking the look of the UAG Hybrid case. I don't own that one so I can't comment too much on it.
