As comic genres and individual issues get more and more expensive, I think most collectors will just keep grabbing cheap stuff until it rises in value also. Those who have the means will always drive the value of certain expensive comics farther and farther into the stratosphere, but many collectors will rediscover the lesser collected (cheap) books...like Archie, Westerns, Four-color, etc. I would suggest you start grabbing high grade Roy Rogers now...while you still can...You know, there's nuthin' like a good whitlin' cover...
