What I miss and what i want to get next

That all sounds awful.

I don't have regrets so much but I did sell my boxed Intruder for a fare VAME price to a VAME friend. I don't regret it and it was the right decision at the time.

As I now have the Joe vehicle "Big Trapper" I could do with an Intruder Commander to go with it, I do have the Intruder soldier that has the silver outfit but I think it came with both.
Anyway it appears that the world loves this chap nowadays (it wasn't just Cookie and Spencer after all) and prices have gone 'radio rental'.
I still don't like it so doubt I'll get one for what I'd grudgingly pay for one but there you go.
One of the very few times I've sold something from my collection but I'm glad he's in a loving home now. Every cloud 🥳

Nothing like having a family reunion 

In the past I've sold on useful items not wanted when I've bought Ebay lots - I don't regret selling those (apart from the bits I then later needed!!)

I also sold one of my VAM DAKs & Combat Marines - I partly regret selling those, only because they've gone up in value.

I wish I hadn't sold some of my 40th sets though (Brit Officer, MP & Argyle).
