Hey - that Hollywood program did look GREAT. Post your own review once you get it. Also the price seems quite reasonable and it is nice to support folks that still develop nice software for the Amiga platform. Good for you and for the programmer
Scala MM300/ MM400 is also a great program but the dongles are a pain in the tuckas. I have a set of dongles as well
mine is green I think and matches with my MM300 software. I also have some Infochannel dongles that are yellow or pink? I don't remember.
You can run what is called a Dutch Auction on E-Bay where you have multiple items for sale. When you set-up the auction you specify the total number of pieces that you have. If you are doing this altruistically (spelling?) you can post a low "buy it now" price. If you want to squeeze top dollar then I believe you can just set up a starting price and see where it goes.
