Yeah, I got a screaming deal on Ebay for a Neptune, $100 shipped for one NIB after crashing my Seamaster. I haven't built it yet, but it's sweet. LOTS of lightening holes. This is a much lighter airframe than my Seamaster was. It should fly great with nitro, and lend itself quite nicely to an electric conversion. They re engineered the water rudder as well, so now it doesn't have that annoying kick up rudder that failed every flight- it's built into the air rudder. Don't get me wrong, the Ace was cool, but I'm all for improvements. The wheels were unnecessary and the provisions added undesirable weight- it's a seaplane afterall, and most likely the reason you'd buy one is to fly off water exclusively. If you really needed to fly off land for some reason it can take off from grass.
