There is another one called Greatest Airliners 737-400 which I find very good. It doesn't have the failure modes that you can programme into 767 pic bt does have some very nice features, like flight announcements that you can record yourself, full FMC nice overwing views and great sound effects. Think you can order it from Amazon. It also includes weight and balance software and software that allows you to design and use other airline liveries (comes with about 30 of its own though!!)
