I'd stay away from the Quando, and I've never heard of the Suzue. The Quandos are just about
the cheapest hubs you can find. I'm going through a similar situation as you, but mine is just an
upgrade, not a replacement as such.
For commuting, I don't think you can go wrong with the Woods freewheel hub, 7-speed freewheel
and Velocity rim.
Personally, I don't know of any other manufacturers, other than Woods, that are making
freewheel hubs in 126mm. If anyone knows of any others, I'd like to hear about them.
I've been using my Specialized, sealed, 126mm freewheel hub (model?) for over ten years in
Boston traffic and it has been just superb, but they no longer make them.
(Having a Sun CR18 rim installed has not hurt the equation at all).
