I watched Mega Python vs. Gatoroid yesterday. It was pretty decent. Oddly enough it starred Deborah Gibson and Tiffany, the bubblegum pop singers from the 80s.
Edit: Come think of it, Gibson also had a role in one of the Mega Shark films. Might be the one with the giant octopus. Lorenzo Lamas wants to blow up the monster using nuclear weapons and she's all: "No, don't do that."
