However, if you look at those remarks for the NICNT and NICOT, those volumes generally rank #1-3 which is excellent.  So for those two I would make the exception, but only because they are ranked where they are ranked (excellent).  I've bought volumes in sets on Accordance because of cost, and because they were bundled that way.  the pricing is also cheaper in general if you get those volumes as a grouping than seperate. 

I think the addage comes from not getting sunk by looking at a sub par reference book for a sermon and end up hosed because of it.  I bought the hardcover of much of the NICNT because a bookstore was going out of sale, i knew the owner and i got an extremely good deal. (80% off).  Otherwise, i would have waitied for accordance's version. 

I'm still up in the air over the whole paper commentary vs digital commentary.  I think both are great to have.  Sometimes I like the book reading, other times, i like the ease of a search on the computer. 

Thanks for making such awesome products!!!
