I took a look at the link posted by Ricky, but unfortunately I don't read Japanese, I think. Anyhow, I'm interested in a mid-size bag, that can hold shoes, shuttles 3 racquets and that's about it. I've been looking for something that I can pretty much take with me for "emergancy badminton play".
There is a new model (should be come up this year) of Yonex bag in HK which should fit your needs (I currently use it as well). Although it doesn't look as sexy as those directly imported from Japan models, it looks good in my opinion (the entire bag is in deep blue). It is also quite cheap, just costs HK$2xx.
