Batsuit Cape Options?

Hi all,

I need to get a cape for my UD Dark Knight batsuit, but I don't sew, and I can't afford one of coofunkcurly's awesome, albeit expensive capes. With that in mind, does anyone have any suggestions for where to get a cape, or if anyone on RPF might produce a decent cape? Ebay was my first step in research, but the options are all over the place and it's hard to guesstimate the quality. Thanks!
