In the past few years, we have covered plenty of amazing chess computers here. The Excalibur Grandmaster is one of the largest chess computers on the market. It is a smart electric chessboard with an ELO of around 2200 USCF. It comes with 100 level, opening training, hint function, and everything you need to improve your game. It has LCD displays and buttons on both sides to make your life easier.
This chessboard is pretty hard to find these days, but you can always find some luck on sites like eBay.
