Walmart food section, $20, weighs all but my heftiest girl Haurie(she apparently weighs "err")
I think it goes to 2200grams. Eventually I'll get one that weighs up to 5000 grams, but for right now, I don't need it, all but 2 of my snakes are still under 2200 grams.
Cool thing, you can swap it to lbs from grams at a touch. Could be handy if you wanted to see how much chocolate you have on hand after halloween.
