"Worth" isn't really a question in a hobby. Something is "worth" exactly how much interest you have in doing it. f you like the idea of playing with a VT, by all means set it up. Most of what you learn with video toaster is transferable to a modern video editor, should you find video editing something that you like to do.
But I have to concur with the previous poster an a 1200 beefed up is the ultimate Amiga experience.
You might also want to play with UAE, which is most advanced in it's Windows implementation. It does a better job at being an Amiga than any existing Amiga but some folks don't like it because want the old hardware feel. Just remember it's your hobby and in spite of what you read here there's no right or wrong way to go about it.
