Beware the Platinum version. It has gotten slammed multiple times on the other Chan board.
My general advice now is to not spend very much money on grey market Chans. I'm fairly confident that all the Monogram Chans will be commercially available within the next 24 months or so.
The Fox Chans are another matter. However if the Lucy Liu movie goes forward, there's a good chance even they will get released.
If you're looking for a collection under $100 and you don't mind sacrifices in quality resulting from 3 movies per disc, then I'd suggest looking at the Old Time Radio set that Rush has a link to. I've heard nothing but good things about that set.
Alternatively, if you have tapes to trade, you could post a message at www.charliechan.net indicating same and get a lot of movies for just the price of postage.
