Great set. When I first got Logos I also got the BOT version that is 2 volumes. Though I have nowhere near scratched the surface, I began finding used deals on the Yale harbacks. This took about a year to complete. Then last year I saw that Logos had this set for under $400. With a payment plan, and thinking 'that's about $1 a day to have WJE tagged in Logos' I felt that it was a no brainer. Though for reading I use my hardbacks, I like having a Logos window open that follows my current verse with the WJE. So for example, if I click on a verse on John it will tell me everytime that JE mentions that verse in all 26 volumes. The hardbacks are nice, and expensive, so this allows you to also have his works always handy on your mobile device.
