The best cheap modulators you can get, for multiple channels, are used commercial "agile modulators" on Ebay, such as the Blonder-Tongue AM40-550, AM60-550 or similar.
I have not heard of interference from incandescent bulbs. What exactly do you see? Regarding baluns, I typically get better performance from physically larger ones versus smaller ones (if you are referring to 75-to-300-ohm transformers).
