This could actually go in conflicts-in-from-the-cold or scifi, but I guess it fits the PA theme best.
I had been eyeing the Siku 1:50ish vehicles for some time, and finally ordered three from Amazon; I usually ignore the recommendations for more purchases, but I'm glad I didn't this time: the forklift comes with a couple of plastic pallets to carry around, and it turns out you can buy a whole bag of 50 of these - and I did. A bit small for heroic figures, but ok for those closer to 28mm, or in the case of heroics it could be a small pallet.
Here's a pic of the forklift, two of the pallets with a somewhat anachronistic Foundry soldier kneeling behind a pallet for cover, and in the background the bag - which wasn't expensive either, just £10.69 for 50 -
