I agree - I've been in a similar situation where I inherited a huge chunk of Python code that worked great and played a very significant role in our product's core, but was horrific to understand or maintain (in Python, of all things!).

I stuck with it for the past 1.5 years and finally got the green light to rewrite it from scratch. Because I worked so hard to figure out what the hell was going on for so long, the actual coding from scratch took less than a month. Bottom line - if you're being paid well, like the environment and think the company has potential and that you have room to grow there, give it some time before you decide to quit.
