My personal preference is glass over metal, but if you are a metal guy....
I've fished out of a Crestliner Fishhawk. That thing was really, really solid. Check them out, used.
Fished out of a few Lunds. Lower end models weren't so good. Pro-V? Yah, that's a nice boat. Pro-Guide? Yah, nice boat. Should have no problem finding some good used ones.
Don't go near a metal Ranger. They are Trackers with heftier price tags. If you like them, just do Tracker, though I know a few guys that have extreme issues with them.
Now...if you look at glass, Tuffy makes some really nice 16-17 foot boats and their 18 foot tiller model is an unreal fishing boat.
But yah...look used. And when you see one you like, do not hesitate to purchase or it could be gone. And...I'd say look at private sale versus dealer. You can tell right away if a guy loved his boat and took care of it. And...he would probably put you on the water with it to test it out.
