Those are the exact waders I wear in the winter, especially when there's not a ton of walking involved and you're standing in ice water all day. Nothing keeps you as warm.
The rest of the year I wear stockingfoot breathables and wading boots.
If you could only have one pair of waders I'd have a look at a pair of bootfoot breathables.
Still light and comfortable, but the attached boots are better in cold weather and you can layer up underneath when it's cold out.
It's not an ideal solution, but if you're only buying one pair that's the way I'd go.
Cabelas, Orvis, LL Bean, etc.. all make good waders with great warranties.
