Do you need an entire knob set with hardware, or just the knobs? House of Antique Hardware has some knobs within your budget. It might be worth looking on eBay - I found some amber knobs that were half the price of what stores were asking (even after shipping from the UK!) Do you have any salvage or ReHouse stores near you? They usually sell such items pretty cheaply. Lastly, if you're not too picky, porcelain doorknobs are a lot cheaper and would still be within the realm of authenticity.

Not sure where you're at but I think a salvage yard would be the best bet. There are often stacks of lock sets for grabs at the salvage places out here.

Thanks, I'll do just that!
