If you want more than eye candy, try the Dreamfleet. It's miles above the CS, and it books out on the numbers accoording to my US Air manual using -15 engines.
A bit of a personal vignette that may be off the topic of this Captain Sim thread, but I have to say that the Dreamfleet 727 along with the RFP 742 were the two planes that provided me with so much feeling of "virtual accomplishment" that I went out and spent mucho dinero to get fully into the hobby, with yoke, rudders, throttles, corei7 and all. Now I'm waiting for those two airplanes to be updated for FSX.
