If you are interested in getting a copy of the ESV with decent cross-references and a basic concordance included, check out Canadian Bible Society. Their special Pew Edition ESV is basically the ESV Classic Reference Bible, without red-lettering, and slightly reset to be a little more compact, though still very readable.
The best part is the price— $9.99 or $8.00/ea if you buy a case lot (and apparently $8.99 through the website!). As with every Bible purchased through CBS, the funds generated from the sales go toward the work of translating the Scriptures, so it’s a no-lose proposition. I haven’t read through enough of it to know whether it’s the original 2001 text or the slightly revised 2007 text edition; from my standpoint it doesn’t really matter so much. The ESV is the translation used on the bulletin covers we use, the version read during our public worship, so it’s nice for me to have a replacement for my much used and literally falling apart 2001 ESV Classic Reference Bible. I’m more inclined than ever to agree that red-lettering is harder to read, so having the text all black is nice, too.
The only negative is the colour of the cover, which evokes a mildly Pittsburgh Penguins or Hamilton Tiger-Cats vibe. Or, as Kelly noted, a Stryper-ish vibe. Though it’s not quite THAT yellow.
Major props to Canadian Bible Society for making this available in this form. (And to the British and Foreign Bible Society, who, according to the copyright page, were instrumental in making this edition available.) And apologies to my American readers, but CBS material is only available for sale in and to Canada.
