I think even with one or two snakes, a scale is a pretty important thing to own. My scale was one of the first things I got after I got Tali and it was a cheapo 15 dollar one- if she decided to go on a food strike and not eat, I didn't want to have to rely on eyeballing how much weight she lost. And I think for me taking care of her, it's a good thing to know- she's about 200grams so her prey should be about 20-30grams. It's easier for me to explain to my pet shop 'I have a 200gram bp, and her meal needs to about 20-30grams' then 'I have a BP whose about :makes gesture: this fat.' Plus, when/if I start ordering feeders online, all it lists is grams, not size. If I have an idea of how much she weighs, I can figure out what prey she needs better then just guessing because I AM a newbie and I don't breed. I don't know the average sizes and how they relate to each other, so for me personally as a newbie, it made a lot of sense to get a scale.
