Hi Matt
First things first: Welcome to Warships at Armorama 

Now for the 1/35 Fast Boats issue:
ADV/Azimut have produced a limited edition of an S-100 Schnellboot that sold like hot bread and have now reached the astronomical value (in some websites) of US$1200.00 (Yes! Twelve Hundred US Dollars!!)
As you may know (the older ones, like me!) Lindberg produced a "thing" back in the 60's, a Elco PT-Boat in 1/32 scale that today reaches the US$100.00  easily, and then you have to face the upgrade and scratchbuilt to make it accurate
To my knowledge no plastic model of a MTB in this scale was ecver made, but we can say that it would be the smallest of the batch, unless we are talking of a Farmile D (or A, B, C...) which is also a good subject negleted in most scales [WEM, I know you have them in 1/350  

]
So with the two above mentioned episodes of the willingness of modelers to have a big fast boat in a big scale is welcome! Otherwise, I doubt that a Lindberg 1/32 Pt Boat would reach the hundred dollar barrier!
Another sign that these could be hot sellers, is the success of late Naval models in this particular scale (LCM(3) and LCVP) and I am only mentioning injection models...
If a Reich Locomotiv, two huge rail guns sell why not these? 
 
 
Just my two cents (on someone looking for an ADV/Azimut S-100 for too long)
