I bought that Epson multifunction 3640 printer after finally retiring my old school tank 990 that still works today. Its very hard to find decent aftermarket, new, or used carts for it now but it still prints awesome when I do get a good cart for it.
New printer does everything and with some tweaking prints as nice as my 990 and double sides everything including scans, and even auto loads up to 100 sheets to be double side scanned and can work with Tablets and phones wireless. There are already aftermarket bulk ink tank setups and carts for it but I haven't run out the starter carts yet, plus OEM ones are 60 at Costco for a multi pack.
Screw HP, new printer only cost 94 bucks at Costco so worth a gamble and so far happy with it.
