In the market for a brew kettle!

I am looking for a bigger brew kettle on a budget...  I am planning on staying with 5 gallon batches for a bit, but would like to be able to grow into all grain brewing as I gather more equipment and experience.  So if anyone knows of any great deals on a keg I can convert, a converted keg, or a screaming deal on a kettle, that would be great!

Thanks!
