Screen/Storm Door Hardware?

I work for a custom door manufacturer. We sometimes make wood storm doors to go along with our entry doors. We make very high quality product so I'm trying to find a storm/screen door latch/lock that is also decent quality while not being over $100. The storm/screen doors are usually 1 3/16" - 1 3/4" thick. I don't have a preference regarding whether its a knob, lever, push/pull latch, etc. but it needs to be good quality and have several finish options (we use oil rubbed bronze a lot). Anyone know of a good supplier? Preferably somewhere online that you can purchase easily. Thanks so much for your help.
