Overlook collector's editions worth the price?

I'd appreciate any thoughts on this. Are the Overlook editions (The Collector's Wodehouse) worth the extra cost? How are they different from Penguin Books' paperbacks?

I'm in the process of accumulating the Overlook Press editions of Wodehouse. I have found several at a local used bookstore at $8.99 per. A great price. Also, many can be found on Amazon or Buy.com at reduced prices. I think they are great editions. I think they have published nearly 60 of them so far.

Happy hunting, fellow blister!
