The change in price points has made it possible for me to jump in, although I am still holding off on the cornerstones of most collections (FF VII, an NES, etc). I noticed those have gone up (well, except for VII, which has settled down a lot).
I use PriceCharting.com and have noticed a lot of the things that went for a lot a while ago have dropped down in value a lot, relatively speaking. I've decided to stay away from the CIBs, though, unless I am going for one of the cornerstones.
