What kayak should I buy?

[Ozwalt]

Hello all. I'm looking for a bit of advice. I'm a fly fishing guide currently specializing in wade trips on the Meramec River in Missouri, but I'd like to add float trips to my menu of services. I've worked out a deal with a local outfitter to rent boats to my clients and provide shuttle service, but I'd prefer to purchase a kayak for myself -- if my client and I are in the same boat, liability goes through the roof. I need a durable kayak with some kind of storage options for carrying fly fishing rods/gear and lunch for 2-3 people, but I'm just not willing to spend a fortune. The river is usually pretty sedate, but there are plenty of log jams to maneuver around. Any suggestions? Many thanks in advance.
