I would advise against the Sure scale. I happened to have two identical Sure scales and they were very off against each other. Will never trust them again.
I currently use an APTP445 scale, which is digital and cheap (more or less $10 on ebay), but works well. It's too thick as it is so I made a step out of a credit card and a little bit of Blu-Tack to measure the VTF at the record level. I regularly re-check it with a 5-gram reference weight and it appears to show repeatable measurements. For those on a budget it's a good option.
