Heck yeah, we live out of those things for the entire moose season here, theres no substitute for hunting rivers and sloughs, getting in and out of boats, walking through tundra, getting rained on etc. Nice chest waders are one piece of gear I absolutely wouldn't/couldn't live without during the AK moose season.
I use Simms g3 but if you don't want to spend that much, I know a few guys with the Simms freestones and they seem to like them. If you are strapped for cash, a pair of breathable caddis waders would work fine as well, I used those for like4 seasons of moose hunting before buying real waders. You could probably even get away with the Simms freestone pants if you dont want to be in waders all day.
As for boots, I'd avoid waders with built in boots, they just don't seem to offer much support, I like the simms boots, Orvis makes an ultralight bot that would work well too. I dont know if they still do, but Patagonia made a good boot for a bit, I know they pmake the patagonia/danner boot but those things are like 600 bucks.
IMO, investing in a good wader/boot system is worth the $$$, I use mine for moose and caribou, float hunts, all summer and fall for fishing and rafting, if I lost or destroyed my G3s, I'd be on the phone ordering a new set as soon as I got home.
