Here are a few items that gave me a moment of pause before I decided not to buy them.
1. Kyoshinhei by Good Smile Company
This figure represents a God Warrior from the Studio Ghibli short film produced for a 2012 exhibit at the Museum of Contemporary Art Tokyo.

At 50cm in height, the figure is impressive, but I have to say that it would be well under it's actual 1/72 height as represented in the short.
The figure is still probably very undersized compared to the original God Warrior as presented in Nausicaä of the Valley of the Wind.
Scale issues aside, the final price with shipping would have been very high, and there was the very real possibility that the model could have sustainded damaged during shipping (polystone resin is not the most durable of materials).
2. Colossal Titan Coin Bank by Bandai
This PVC figure represents the aberrant type 60m Titan from Attack on Titan.
The Colossal Titan at 60cm, is even taller than the God Warrior. It is actually 1/100 scale, but that's something I would have been willing to overlook with regard to a fictional flayed giant.
3. Flower-class Corvette by Revell
Even now, I often contemplate buying this kit, but at 85cm in length I wonder where I would store it. The pool might be an option, but I couldn't keep it docked there all the time.
4. U-Boat Type VIIC by Revell
I would seriously consider a waterline U-boat since they could be used for gaming every now and then, but at 93.3cm long, the type VIIC and the even larger type IXC submarine (106.3cm) are just really big.
I suppose that the kit could be converted easily enough to a waterline model, but that seems almost like throwing away half the kit.
5. Skipjack-class Submarine by Moebius Models
As with the U-boats, I would definitely consider a waterline model of the Skipjack for an Ice Station Zebra scenario, but at 106.7cm, the full hulled kit is a monster. I believe that this model is also sold in Revell packaging.
6. Gato-class Submarine by Revell
Yet another submarine. This time the 132cm long Gato-class sub. If I were to have bought this model, I would have been tempted to get two. One built up in the standard way, and one built up as the USS Sea Tiger from the 1959 film Operation Petticoat.
However, I probably would have been bothered by the fact that the subs used in filming were actually Balao-class submarines, while the USS Seadragon which reputedly operated in red primer color for a time was a Sargo-class submarine.
7. C3-type Cargo Submarine by Lindberg
Lindberg went out of business, but the kits are still being produced by Round 2 LLC under the Lindberg brand name. The model is 148.6cm long, and comes with four Kaiten manned torpedoes.
8. Saturn V Rocket by Dragon
There was a time when I was really interested in getting the 1/96 scale Revell Saturn V, but by the time the Dragon version came around, that desire was a distant memory. At 153.7cm tall, I'm not sure if there is a commercially produced 1/72 kit that is larger than this one.
In closing, I'll have to admit that at times I look at my existing piles of lead and plastic and wonder what the point of it all is. However, finishing a project no matter how small, or getting to play a game with newly painted miniatures always brings a sense of satisfaction, and puts me back to the proper hobbyist perspective.
