The original puma bowie is nice knife but there are better user's out there. They have small handles and blades are to light for chopping but this is a good time to be looking on ebay because these knives are going for lower than normal.
A good user knife that's also nice to handle as well as look at is the Marbles Ideal from A.G. Russell. They now come in 1070-6 carbon steel which has excellent edge holding, easy to sharpen and can take a lot of abuse. They have three sizes 6", 7" and 8" blades. The 7" is my favorite in this knife. Prices are the same as you would be paying for an original puma bowie at approx. $150. Since this a Marbles it will have good collector value.
Also, the OVB bowie's by Camillus Cutlery are very nice. Check their webside for information. They are currently out of stock but a lot of retailers still have them. These blades are lighter weight and have very nice balance. These knife is designed by Fisk and also have good collector value.
Most people use their bowies for chopping and they tend to be a little to large for other outdoor uses. My experience is that a 7" blade is minimum for half decent chopping ability.
If you are not sure about the size that best suits your needs, a good starting point is a Camillus USMC knife for approx. $30. Cut & file the top of the guard off and you will have a good using bowie knife. They chop well, cut well, are easy to sharpen and are disposable when you consider the low price. They use 1095 steel which is a 'notch' better than the 1070-6 as currently being used by Marbles Outdoors.
The 7" Ideal from AG Russell has a thicker blade than the USMC knives and is slighty better for chopping due to it's heavier weight.
The new Puma bowies use regular quality stainless steel but are nicely made for approx. $70, if you shop around.
Good luck with your search,
