I use similiar cheap ones..I've had it break before but that was my fault, and I think they are fairly accurate as I've measured pennies over and over and it gives consistent results, and shows the weight pennies are supposed to weight - which varies a little bit.

Of course it depends on what you are want to do with it, and how accurate you want your reactions to be.

What kind of scale are you talking about? Electronic , digital, triple beam ect.... how deap do you need it to read? All of this is going to be a factor as to weather or not the scale is worth it.
My personal favorite type of scale is triple beams but that got confiscated so not im just living with a cheep 10$ harbor freight digital and ill have to say its not working out to bad either. 1/10 gram depth is good enough for me at the time being.

I have no experience with that particular model, but a 0.01 g x 100 g for 16 pounds sounds like a good deal on a useful balance. A little more capacity would be nice, but the advertised precision seems quite good for the low price.

Hell I didnt even see your link the first time there dude. I seen the scale in question now and Id say go for it and give it a try. worst case situation is your out a few buck but best case is it works fine for a while and saves you the 200-300$ pricetag that simular scales with that form of precision have. Honestly I think Im going to pick my self up one.

I have one a lot like the one shown I got for $15US. I use it for weighing fly lines. I check it with an Ohaus callibration set of small weights. It never seems to change and reads accurately.

If you want to measure very small quantities, buy a old mechanical Mettler balance off of Ebay. I purchased mine for around $50 with shipping several years ago. It works great, but you cannot just press a tare button. The balance weighs down to .1 mg and up to 160g. One of my professors told me that the old mechanical balances are more accurate then the newer digital scales.

I had experience with the 0.1g models.
they are ok... however be prepared to buy them every 6 months because they do tend to brake, either they just ware down very easily or I'm just really careless

I've had a cheap plastic $30 one from ebay for quite some time now, and it still works perfectly. Measures out to 0.01 and has always been precise and accurate enough. The only problem is that the weigh surface is quite small.

The cheap ones for weighing a few grams with a resolution of 0.01 g are pretty decent.

However, I would stay away from the 0.001 g resolution scales. I had HORRIBLE experiences with those and had to send a few of them back. After calibration, they wouldn't even measure the calibration weight accurately nor precisely -_-

Also, a word of caution about the old Mettler balances. Though they are extremely accurate (resolution of 10 ug), they can be a huge pain to use because the slightest movement messes them up so you will have to recalibrate often (or keep it on a concrete block).

There is this one site- dealextreme.com

They have some really cheap small electronics on there but get this: everything is free shipping.

Anyways I ordered some stuff and it take a while (cause it is straight from china) but it came and it worked really well actually. They also have a bunch of other random crap that is cheap and useful.
