Sometimes wish I'd bought a M61A5 back when. I still might, if they become available again.
I got mine on sale cheap a couple years ago from Amazon. I actually bought two but sold one last year. I wish I held onto it now because they are selling for almost $300 USD now. Well, I should say, they are asking almost $300 USD now but not sure if they are actually selling at that price.
The M61A5 is really cool! It is a huge tank though. Here is the Bandai 1/35 M61A5 next to the Academy 1/35 Merkava Mk.IID.
Next to the Tamiya 1/35 Leopard 1A4.
Next to the Panda 1/35 T-15 Armata. The T-15 is huge as well.
