PLCLogix RS5k emulator /simulator

I have been looking for an RS5k emulator/simulator similar to the ones for the RS500 offered on "The learning Pit." I came across PLCLogix the other day. By the description it seems like just the product I am looking for. However I thought I would ask if there are any users that tried this product or a similar product and whether they have any recommendations before I invest $300USD on this product.

Thanks Glen

Here is another option. A little cheater.

Note: I have not used it.
