Sink Update

Well, I spoke to soon. The sink kept leaking, so I went out and bought some more stuff and tried to affix the nut using pipe compound and thread seal, using a fancy new plumber's wrench. It still came undone. So I broke down and had a plumber give me an estimate today. He confirmed that the strainer itself was stripped, and I'd need a new one. He quoted me a price I thought was way too high, and I counter-offered. He accepted. Everything now works. But I do feel bad I'm out the money and that I didn't try to replace the strainer myself. I just couldn't take the thought of another trip to Lowe's and then coming upon yet another issue.
