I did purchase and download Counter Collection 4th Edition Heroic 1 yesterday as part of the GM's Day Sale at DriveThruRPG. I also managed to find the time to print out and mount some of the counters. Below are a few shots of my handiwork. NOTE: the tile pictured is NOT part of the set. I just used it for 'set dressing' to see how the counters would look on the tabletop.
The counters are pretty neat. The art is slightly 'cartoony', but does a good job of representing each 'heroic tier' creature found in the 4th Edition D&D Monster Manual. I also like the little spot on the counter for writing a number. Very useful for keeping track of that horde of minions.
I mounted mine on plain old pasteboard box style cardboard. This seemed to work out pretty well. The tiles are light, but thick enough to pick up easily.
If you are looking for a cheap and attractive source of counters for your 4E game, i recommend that you check Counter Collection 4th Edition Heroic 1 out. I am very pleased with my purchase. And the price was right!
UPDATE: For those of you that would prefer the convenience of a pre-printed version, Jason of Fiery Dragon Enterprises reminded me that they now offer a boxed version of the 4E counters that are already diecut for your convenience. Check them out HERE.
