Ebay sellers....what kind of scale do you use?

I am looking into a postage scale so I can start selling things on Ebay. I live to far from the post office to make quick trips in for a quick way ( our post office rarely has lines of people.)

This is one I’m eyeing.

As well as this

I will probably never sell much of anything over 20 pounds, but in the rare instance, it would be nice so as I wouldn’t have to guess.

I will probably be selling mostly books, kids clothes & toys, misc household items at first.

Thoughts and suggestions recommended.
