For my feedee, she knows I do a lot of looking. Reviews are always helpful. Make sure you find ones that can actually support a certain weight. If it says 400lbs weight limit 50lbs over is likely going to make the battery stall quite a bit.
Also batteries! These will be quite expensive and need replacing often. Make sure you find ones where it won't be too much to install a new battery. They can cost around $125 each.
So one major key is to respect the weight limit. Got it!
