P-Touch Cube Plus PT-P710BT and Brady BMP-21 Plus
P-Touch Cube Plus PT-P710BT - Flat stickers only
It accept a wide range of material up to 1" wide, has an internal battery, and can be used either connected to the computer or through an app on your phone. Way faster typing on a computer keyboard than small buttons on a label printer. I used it for all the labels on my panel (white on clear tape) and recommend it. Cost around $100
Brady BMP-21 Plus - Flat stickers and heat shrink
This works great and is reliable but has its own keyboard that is slow to use like so most label printers. For additional $ you can get a wall wart for it but otherwise it uses AA batteries. It does both flat stickers and heat shrink. I like it and would recommend it as quality so good but typing is slow. Cost around $120
