I do have a million projects going at the moment, but am considering another and wanted some feedback.

The interior doors in our old 1930s home are solid core. Unfortunately, they are also beat up and have too many layers of paint on them.

Options:
1). Refinish the existing doors - lots of work, probably lead paint, some would have to be replaced anyways

2). Buy new prehung doors. Hollow-core seem cheap and noisy to us and a downgrade for the style of home. Solid in the right style are too much $$.

3). Build them myself. I'd use poplar as they would be painted. Joinery would be mortise and loose tenon.

We are talking 9 or 10 doors total. What do you think? Anyone make the same decision? It's sweat vs. dollars.
