Check out this model, The Weller PSI100K - Super - ...
This Portable is rough and tumble tough and travels well without being in a protective case, It takes up the space of screwdriver and the vented cover makes it travel ready just after the job is done!
After many years it's still currently available, Reliability beyond my expectation, long tip life and cheap to fill using a UN2037 portable gas range cartridge.
Did I mention that I might be satisfied with this product
