Russlock or a Sod Buster are also great choices, just keep in mind that on recent production models, (in the last 10-15 years
) QC has left F&F inconsistent at best, it's always best to handle and personally examine the knife before purchasin' it.
If you do buy of the internet, check the return policy, customer service, ect, some places have restocking fees for returned items and always make sure you pay with a method that leaves you some recourse should you have a problem with a shady seller or dealer.
Otherwise enjoy the variety that the Case brand has to offer, also look into vintage gently used Case knives, I still occasionally find 'em at yardsales and fleamarkets for under $10.
