Currently if you want a large Wash and Cure station the Anycubic Wash Cure Plus ($250) is the only one available right now.

Depending on what you're going to print you might be able to get away with one of the smaller wash and cure stations from Elegoo ($109) or Anycubic ($129). Or you can DIY one.

If you're going to DIY. This container ($13) fits the Saturn build plate,https://smile.amazon.com/gp/product/B000KHRXA8/

You can cure prints in the sun or buy or build a separate UV cure station like the Sunlu ($39),https://smile.amazon.com/dp/B08P7CMR1Q/

I would also, start with Elegoo Standard resin it currently $26 per 1kg https://smile.amazon.com/gp/product/B08T1BBD81/
