That's your opinion and it is as valid as the next persons. But I should state that with Spaghetti you continue to get free updates and I try to add features that customers request. For example, I gave you 2 extra licenses for free to work in your environment. From the time you bought your license I added things like DMX, TTL, multiple projector support, text, effects layers, video output. I'll also soon be adding a laser camera application, windows media plug in, ILDA file optimization, and some other extras to the application suite for free. Additionally, I will be adding another feature that I am not able to talk about right now that you will not have with Quickshow but would be very cool for you since you have a sound card. There will also be a live player to go with it sometime in the future.
Quickshow is a nice package from what I have heard. But, the DAC itself is costs about $50 to make, if that. Enjoy your $550 Quickshow application.
