I own the Tracker Knife by TOPS. For what I use it for it's great. Big, hefty, good for chopping and primitive tool making. I carved a decent atlatl with it, and my wife finished her yew bow with it. I've abused this knife quite a bit. It is a bear to sharpen, so I have it done professionally. Other than that, I have no complaints.

I don't own any Tops knives, but looks like they make two Anaconda's... the Model 9 and the "B" model (Model 7). The first one has a good blade length, but an awkward curve for chopping purposes. The second has a great curve, but the blade is only 7", and I'd prefer 9" for chopping. If you plan to do any gutting, whittling, or carving, you'd be best off with a smaller knife (like a 4" blade) that specializes in those areas. Otherwise, they both appear to be pretty well made- full tang, micarta handles... What would you be using it for?

As for the Tracker knife, what I hear is this. As far as individual tasks are concerned (chopping, sawing, fine wood-work, etc.), there are much much better knives out there that specialize in these individual areas. But it works okay if you're looking for one knife to do it all (definitely better than those multi-purpose rambo-style "survival" knives). Most people seem to be of the opinion that if you have the option to carry more than one knife, get several that specialize in different tasks. But I would be curious to see how it handles... seems like a decent back-up knife.
