External Game capture?

Im looking for a good and easy to use Gaming recorder. Ive looked at the -Avermedia- Game capture but the cost is just too high but i heard it is easy to use. Ive looked at programs like Fraps or other things like that but i just cant get the setting right and it takes too much space on my hard drive. I need it to be able to capture at 1920x1080.

Have a look at some BlackMagic equipment, it's quite pricey in some cases but i've heard great things.
