Large metal reflectively lined thermos bottles are worth considering.  You do
end up with a lot of long skinny circuit boards that way.

Peltier based thermoelectric cooler's from Big Box Stores can also be
pressed into
service as temperature cycling oven, or stable temperature environment, with
the addition of proper regulation loop.

H-Bridge Motor Controller and a Thermoelectric Cooler".

Next time you have to endure shopping with your wife keep your mind busy by
asking "What can I use 'that' for?" for everything you see...

The Preface to Murphy's Law:
 We, the willing,
  Lead by the unknowing.
   Are doing the impossible for the ungrateful...
    We have done so much for so long...
     With so little...
      We are now qualified to do anything...
       With nothing...
        Forever!
