I have noticed many people commenting on the lack of funds for a digital scale with which to weigh their snakes. I wanted to recommend ebay for this purchase. I recently bought a scale for under $20 which weighs up to 36 lbs in 0.1 increments in lbs/oz/kg/g. It zeros/tares out so that I can put my bp in a small tupperware to weigh him accurately and is great. the one I bought was a DigiWeigh postal scale just like this one http://cgi.ebay.com/36-LB-DIGITAL-SH...item5193d38d17
Hope this helps!
