My Xpress XP18CC has been a great boat in the 4yrs I've had it. I don't abuse it, but I don't baby it either. I shopped comparable boats from the major manufacturers and it came down to the G3 or Xpress, Xpress won mostly because no G3 dealers around had any CC's I could see in person.
Lowe seemed to have an above average amount of bad reviews for broken welds and was priced a bit high IMO. Tracker wasn't really even on the list after the first look at their boat, design & build quality is horrible on the Grizzly CC. The only one I wish I had paid more attention to was Alumacraft. Sea Ark is a nice rig for sure, but you'll pay considerably more for it too, just wasn't in the budget, and another case of none to actually see before the sell.
If you're not living on the edge, you're taking up too much space!
