Fellow boglehead here with a question: What is "low cost" in a broadly diversified ETF for you? Obviously a TER of 0.07% (WEBN) is low, but is 0.19% (VWCE) or, say, 0.25% (XMAW) still considered low? When do things start to be no longer low for you? And do you consider anything else in addition to TER wrt cost? Thanks for your insights!
