Nothing too wrong with what you have listed there Az, I quite like the sea plane models in particular for a cheapy.
I had a 9'1" Chinese made Modern longboard for a while that I got cheap second hand and it went pretty good. It was a Blackbird model made around 2013. It turned and paddled well plus could noseride with ease for me, fin set up was Tri fin and worked best with the large centre fin about halfway in the box.
