I've been a fan of Akai's MPC drum machines/sequencers since I bought the very first MPC unit they released in the '80s. That MPC-50 lasted me right through into the 21st Century, albeit with a slowly increasing number of faults due to age and constant use. It eventually broke down beyond sensible repair a few years back and I replaced it with a second-hand MPC 2500, bought from eBay, which I've used ever since. Akai had stopped making stand alone drum machines and instead went down the computer software route, making hardware 'controllers' to operate software drum sequencing and sounds stored on a computer or laptop.
Not being a fan of making music this way, this system didn't suit me, hence having to buy a second-hand MPC 2500, which was one of the last 'stand alone' drum machines they'd made.
