solder-Eutechnic,Wonder,WBT??

Just ran out of solder and was wondering what to purchase as a replacement.I understand the Mundorf is highly recommended,but would prefer to stay in the "modest" camp.
I have a few projects that I am working on and the last of the parts will arrive later this week.
Prefer one that will not add brightness and those that do not contain any gold,as I don't like the sonic flavor.
Thanks in advance,Tom
