canare plugs are pretty decent.

If you want something that is reasonably priced and will break someone's skull, try the switchcrafts, never fails to impress me.

Don't use Silver solder. It's really not worth it due to it's higher melting point and the pain in the ass to stick. There is no substantial improvement either and it usually kills quality instead because of the difficulty to produce consistent results.

use high quality euthethic blends.

what's wrong with having a little lead

Anyway, you can try the Kesters 63/37

I use the Kester 245 myself.
