I had extreme cash flow issues last year, so I got the Bi-Mart neoprene waders last season. They worked for me, but did develop a crotch leak.
Now that I have breathable though, I wouldn't go back. If money is an issue you may not have a choice (trust me, I understand), but if you can go at all over budget, even low-end breathable would be better in my opinion. The neoprene would leave me drenched in sweat at the end of the day, especially if there was any hiking involved.
