I can maybe get the Weller WS81 for around 189USD, is this a good deal?
It sure seems like it.
Furthermore is it problematic that it's analog instead of digital?
Not if you want it for its intended purpose - soldering.
A digital readout doesn't improve your soldering in any way, and you will soon get a feeling for setting the temperature without the display.
If you get this, you should have a tool that will last you decades.
Remember to get tips of different diameters - narrow tips for fine soldering and a large one for when you need the heat transfer, like soldering large connectors, cables or metal sheets.
Keeping your tips tinned and in good shape is important for ensuring their longevity.
