The insulation is the key, so it's either make one or buy one - hassle
factor is significant here as I have a *lot* going on right now.

Insulate the Daleks with something like loft insulation strapped
around them. A couple of rolls will be much less cost than buying a
Hot Bin.

Hot water tank blanket? Although the insulation is somewhat useless if
it gets soaked with water and remains wet.

I did wonder about that as an option, but the Dalek shaped composters
are a large and uneven circumference bigger than most domestic hot
water tanks, especially around the base. ISTR the blankets are not
that thick either.
The point about the insulation getting wet is a good one,
Until I found that burying the compost bin in the middle of the grass
heap worked well enough I was going to wrap it with an old roll of
insulation we had and then use some large sheets of bubblewrap that we
used as green house insulation one year but are now surplus , that
would have given a degree of water resistance, some bin liners and
sticky tape would do the same.
Or the OP could just buy a wide screen telly and use the packaging to
make a Hotbin
