You can find all sorts at all sorts of prices, I have a 2 year old pair of Redheads from Bass Pro shop. I think I paid $70 or so for them. Their 3 ply and lined, the shoes are felt bottoms. I use them for fly/trout fishing in Tennessee and the Carolina. If I remember right I could have gotten lugged soles on the shoes for the same price.
If you've got the time google on line, you can have them in a couple of days.
Stone Creek waders at Academy are very reasonable and will keep you dry. They sell both the stocking and boot foot. My preference is the stocking foot, the seams where they attach the boot foot can rub the hell out of your legs thus having the need for $12.00 wading sock that get harder and harder to put on after a couple of washes.
