Pontoon Boats- who's had one or currently does and do you like it?

Times are changing and I need a way to get my dad on the water before it's no longer realistic. Bassboat is no longer an option so that may go up the road but I am thinking a 20ft. Pontoon may be just what I need. Mainly fishing smaller bodies of water (mostly fresh and a little salt) and am needing it light enough for my V8 4runner to tow it.

I don't want someone's used and abused headache so a low use one is probably in order and that's OK to. I am not against buying a new one however the Duster will need a new home and that's OK to if that's helps to finance one.

I am pretty happy with my Mercury's however that's always a debate but what brand is the best bang for the buck in regards to the pontoon itself?

Thanks,
JW
