A friend of mine is a manager for Office Depot in the inner city. He said that his best selling items are the scales.[/QUOTE
The shelves that usually hold scales in our local office supply stores are always bare with only the most expensive models in stock. I am sure some of those guys twisting off are snatching them up, but I bet alot are from fleabay sellers also. Not to mention they are used in several hobbies, and bussiness, as they are in cuebuilding.
They can be found on ebay as mentioned. some digital scales even have a fixture to hold tube mailers, so would be easy for the person such as a dealer to get a quick weight on a cue without It rolling off. Sure they come in different measurements. They might be alright for a cuebuilder, but I used tripple beams in school years ago, and they were very accurate, nothing compared to them at the time. If It's for duel purpose, and you will be weighing packages with It, then the digital will probably be more suited.
