EPSON WorkForce ES-580W. Got it from eBay with "damaged packaging" (not really) from Epson Outlet Store in my country. With a discount code I only paid 324 €. There is also an official promotion by Epson (in Europe only maybe?) where you get 75 € cashback for this scanner, so effectively 249 € which is a VERY good price. Also supports SMB but I'm running Paperless on my VPS, hence I used WebDAV (if you do this: the scanner will do a GET request to the WebDAV url first which must be answered with a 200 OK or it will never try WebDAV).

I debated between this scanner and the Brother ADS-1800W but the Brother has a slow UI and no thingy where the paper lands when it's done scanning (not sure how it's called in English).
