I just ordered the 6-DVD "Mr. Wong" set from Amazon. It was a little more pricey, but I thought it preferable to the evidently single DVD containing all six adventures which is less expensive. The latter, however, does contain some extras that the former set does not, and the reviews from buyers reveals its good qualitiy.
As Steve notes, we will be viewing other adventures from this collection later on, and we will be comparing them to the Chan versions!
Thank you so much, Steve, for your very helpful recommendations...
I just saw on Amazon that if you are a PRIME MEMBER (you pay a yearly fee for shipping) then you can stream the Wong movies legally and free! Not a bad deal if you order from Amazon a lot.
