If it was $5000 it would be worth it. But $30 is probably a great price on average.
I recommend the set. If you get it in one big volume you would probably wear out the binding pretty quick if you use it as much as I do. Also, in the big volume the type is quite small and hard to read.
Dont bother with the concise. It's Matthew Henry lite, and you subject yourself to what the editor thinks is important, and miss out on a lot of treasures that Mr. Henry had to give. Also... the concise will run ya $15 - $20, so spend the extra $10.
Pro... MH had incredible insight. His commentary is very easy to read, but at the same time incredibly deep. It's very good as a devotional if you're sick of all the "10 minutes with God" devotionals that are out there.
Con... MH does lean some toward Calvinism, but I dont think he was a hard core Calvinist. I think he was very balanced. Some others might disagree.
Any other commentary that would be better? Other than the Bible istelf, I cant think of any.
BUY IT!!! You'll love it.
