If you think the original poster should buy a particular engine, or if you have any other advice for setting up a good trainer, simply explain why.
Who are you, the Post Police? It's no skin off your nose who answers the OP and how they answer. At least those who made recommendations added to the thread and didn't simply just criticize the other posts. Seems like the pot is calling the kettle black...if YOU have something to say that's germane to the OP's questions, then please jump in - otherwise...
