nothing really "wrong" with the AEM pullies. Just some people think that they are overpriced for what they offer. As it is it is going to cost you a bit to get the belts, pulley, and key...i think that is all the other post was saying....is save your cash in case something in the engine was damaged. most honda engines have 0 valve lash tolerance...or something like that...it basically means if you loose the timing belt or crank pulley your pistons can smash into your valves which smash into the camshaft and your whole top end is totalled..worst case scenario of course. most of the time there are just a couple of valves that are bent...but that is still costly to repair.
