I'm not sure what you are asking. Would your Paulaner bottles take standard crown caps?
I save standard long neck brown bottles when I can, but I also have lots if shorter bottles (I think they are referred to as "heritage" bottles). Sierra Nevada, Lagunitas, and Founders all use these shorter bottles and I frequently buy from these brands.
Anchor bottles also have a different shape. They are shorter (like SN bottles) but have a more gradual taper.
I have some stubby bottles as well (like Red Stripe) that North Peak brewing here in Michigan uses.
Other than reusing commercial bottles, you can get new 12 oz bottles for about $0.50/bottle, but add shipping to that from an online store and it's pretty much $1.00/bottle. They usually have standard long neck and also the shorter "heritage" bottles.
Your best bet is to find a LHBS that sells new bottles. You can get a 12 pack of them for about $25.00.
