T.B.
I second the suggestion of Miche bags. They have 4 different sizes and a TON of shells to go on them. Also, if you search eBay, you can find the base and the shells (some original, some home made). I got my bag and 2 covers for around $60. My sales person has sales a lot where she will get rid of old shells for really cheap, so I have bought a couple more that way.
