After trying out a few different knobs, we decided on these small oval birdcage knobs from Liberty in antique pewter. These are nice because they can be used vertically for cupboard doors or horizontally for pull-out drawers, so have an updated look to them. They also worked with the original screw hole, so did not require extra holes or patching. Last, but not least, they are just pretty. Did I mention there are 45 knobs to replace?
Here is a picture with the new knobs and paint job, so far, in Benjamin Moore Titanium:
