For me, I'm not a huge stream/river guy but I bought a pair of waders with boots attached for like $65 bucks at sports authority 2 years ago. Similar to these

I've honestly never had a problem. I got a size bigger for the cold. I'm 5'10, but weigh about what you do and I got the XXL and when I've gone with an underlayer I've been warm and comfortable. Again, I don't use them too often so if your gonna do a lot of wading, I'd listen to some other guys but these have worked for me.
