I have a dilemma and am hoping to solicit some advice from those who have experience in this area. The problem is this: I need/want a good all around fishing boat. I have narrowed things down a bit in that I'm looking at welded aluminum between 14 feet and 19 feet. Originally I planned to used the boat only in the salt and in various lakes (I already have a drift boat to float the rivers). Lately however, I've been getting greedy and thinking I could get a boat that can handle salt, lakes AND rivers. My questions are as follows:

Am I asking for too much?
Any boat brands/models that people recommend?
What are people's experiences using a jet in both salt & fresh...good idea/bad idea/stupid idea?

Any and all opinions are appreciated as I only have so much space in my garage and/or backyard.
