Check out any of the Tascam DP series recorders. My first recordings were done with one of those, and used it for nearly ten years until I could afford a PC to record with. I still use one now, the DP32SD, in combination with my PC. The latency is too bad to record well with this PC, so I use the Tascam for tracking, then mix and edit with Reaper. You'll have to memorize menus and buttons though.
The newer models record WAV files to SD cards, so it works out really well. Unfortunately the newer models also skimp on the physical controls, but it's still very usable for just plain tracking. For example, my first model had a physical channel strip with pan, reverb, high/mid/low EQ, and send/return controls for each channel, but my current one has a single channel strip that is reassigned to whichever track you want to edit. It's easy enough, since each channel still has a select button above its fader, so all you have to do is press one of those to assign the controls. Another example of how intuitive it is: to assign an input to a channel, you press and hold the select button for one of the inputs, then while still holding, press the select button of the channel you want to assign to.
I've also used the Zoom recorders. The handheld H recorders are good for recording a single simultaneous take. In my opinion, overdubs are too much trouble with those, considering you could get one of the smaller Tascams at that same pricepoint that's much easier to use. The Zoom R series are also difficult to use, since the menus wrap, so you have to remember where in the menu you were when you last used it. With the Tascams, you can spam the cursor keys to get to the top of the menu if you lose your place, and the cursor will stop at the top of the menu, while the Zooms cycle back down to the end of the menu.
