I appreciate what you guys are saying but I'm really happy with my i2500 that I bought direct from a website www.cyberscale.net
Whereas your scales read to 0.1oz / 1 gram, the i2500 reads 2500 grams in 0.5 gram increments / 0.02oz
This is REALLY a lot more accurate and perfect for making the best espresso that my friends and family have ever tasted. If you mix, you need something more accurate then 1 gram for sure :)
It is really nice to be able to sit an empty measuring cup on it, hit TARE to zero it out and pour in the beans. I'm an air popper guy, so I normally roast 3 grams (approx. 1/2 cup) which normally comes out as a cup of roasted at 2.5-2.7 grams.

PS: An alert reader pointed me to the Brand Commentary section of DigitalScales that has some interesting notes on this industry. Nothing is ever simple it seems.
I have an AmericanWeigh which is decried on the above mentioned site as being produced in China. So what, nearly everything I own (except my China, strangely enough) was made in China. My scale functions very well and even has an on/off switch. It is inexpensive and comes with a 10 year (or until the seller goes out of business whichever happens first) warranty.

I have seen that very scale at Office Max, and I also just looked at the online description. It has a sensitivity of 1.0 grams, not 0.1 grams. A 5 lb scale with a sensitivity to 0.1 grams would indeed be a bargain for $ 25, but alas, this is not the case.

0.5 cup by volume is about 3 ounces by weight. So I am certain he is reading '3' on the scale, it is just set on the imperial, rather than the metric, system.

Does the scale HAVE to be digital...what about a standared Ohaus Triple Beam Scale or similar. They are marked to .1 gm increments (actually since it is analog you can actually measure by eyeballing it between the marks to 2x or 3x better fineness than that...should you wish to get really anal retentive when measuring grounds for brewing). Not sure about prices today...paid 60 bucks for mine about 12 years ago and it is a tank...very reliable....pricey compared to others options mentioned here...but it can wiegh a full lb +...610 gms total.
I will second this suggestion. I got mine for $35 off of ebay. They're practically indestructible - mine was poorly packaged for shipment, yet it is still very accurate despite the added abuse it received in shipping.
For less stringent accuracy requirements, I have a pelouze digital postal scale. It has that annoying auto-off feature, but at least it gives me a couple of minutes before doing so. Others I've owned would auto-off after only 15 seconds.

DigiWeigh (China) makes a great digital balance. They have a couple of different pocket models. I have the 1000 x .1 gram. 1) Price - 20 USD 2) Modes - grams, ounces, dwt, and ozt. 3) Power - 2x AAA's 4) Tare - one button or at start-up. 5) Vendor - eBay
I use mine every day to weigh 72 grams of roasted beans into my grinder, and a couple of times a week to weigh the green beans.

It is also stable but can be sensitive to static fields (like when weighing an AeroPress, it's possible to get a few hundredths of a gram drift because of static).
I rarely have to re-cal the SC2kg, the SM-501 I probably re-calibrate maybe once a week when the cal-weight reads 499.92 or so, or the 200g cal weight is off by more than 3 hundredths.
Both auto-off in 1 minute if no change in reading or input.
Both are sensitive to the temperature of an object being weighed - I use a chunk of blueboard as an insulating tray to measure a hot cup of coffee, otherwise the zero will drift (and return once cooled again - I'm sure it's thermal sensitivity to the load cells).
