Bug Tracking systems

[figment]

Need a few opinoins 🙂

Does anyone have any advice on a bug tracking system to use?
Preffer free, and preffer PHP based, without the need for a subscription (Bugzilla), but will settle if need be.

Here are some requirements:
System must be able to enter bugs with a complete description.
System must be able to delineate a product name, version number and unique product ID.
System must be able to Set status of the bug in some variation of the following states:
- Reported
- Verified
- In Development
- Resolved
System must be able to record notes so that a history of what was done and when it was done is kept track of.
System must be able to report on and sort by various pieces of information.
System must be able to assign bugs to individuals – E-mail notification would be nice, but not necessary.
System must be able to assign Bug Level of Priority (Hot-Warm-Cold).
System must have a User Based Login.

Is there anything that comes close to this? I've read a few feature lists, and had things that came fairly close.

Or would it be more worth coding something like this from scratch?

Gosh, not asking much. I wrote something similar using a guestbook tutorial as a base. It was very good experience.

But no, it's not good enough to publish but we like it.

There is one called TrackIt, Don't know where you can download it from, sorry, but google might. A working version is about $60 i think.
