If looks matter to you most, consider a rotating waffle maker. Because you flip the iron over as it bakes, the batter can become more evenly distributed over the grates. That being said, if you really want picture-perfect waffles, try our Lab's even-heating hack: After pouring waffle batter over the hot grates, use a rubber spatula to gently (and quickly) distribute the batter evenly across the surface before closing the waffle maker's lid. You'll never have to eat a waffle with absent, sorry-looking edges again!
Waffle makers can vary widely in prices. More affordable options go for around 15-30 dollars, while if you really want to splurge you can spend as much as 130 dollars. For basic waffle making, a cheaper unit works fine. However, you do sometimes run the risk of it breaking after a few months because of lower quality parts. If you feel like getting fancy with variable temperature controls, flip plates, or the like, it will probably cost you a bit extra.
