I have used a cheapo saike hot air station from eBay for years mostly for heat shrinking duty which it excels at and it’s never missed a beat for my light duty use. Mine has a digital screen but it’s not really needed as I always run it on full air and highest temp. I can see something very similar but without the screen on eBay for £20 posted. Might be worth a look.
