Sure. About $40. 3Kg max, 0.01g accuracy, came with a cover, two calibration weights, power supply… scale pan removable for cleaning. Really excellent. EBay. https://www.ebay.com/itm/292651747068?ul_noapp=true
Seriously good purchase. -
I have three from AliExpress.
One has 0,001 gram accuracy with a 50 gram max (± $20), 0,01 gram accuracy with 200 gram max (± $5) and 0,1 gram accuracy with 2 kilogram max ($7).
The first (0,001 gram) can be adjusted (levelled) and calibrated and came with a calibration weight. Other 2 can also be calibrated, but didn’t came with calibration weights.I’m very pleased with the scales.

And many times there aren’t even shipping costs (AliExpress).
The only thing you need is patience. It takes about a month before you receive the item (sometimes 2 months, other times only a week).
One advice: never buy glassware there. There’s a 50/50 chance to either receive the items in perfect condition or get them in a thousand pieces (it’s easy to get a refund though). This really depends on the individual seller (some are way more thorough and careful than others) and the value of the item that you purchase (and the ordered quantity). They won’t put a sturdy box around one or two watch glasses for example. -
Glassware. I have one, 2L, Chinese beaker left. They are too thin and easily break. Pyrex beakers are expensive but thick glass and good quality.

The only glassware I bought there are volumetric flasks, glass stirring rods and watch glasses. The volumetric flasks arrived in good condition and seem less fragile than I expected them to be. But incomparable to brands like Pyrex or Duran of course, which are top notch. -
I would go for it.
But, I have seen balances in laboratories that are well over 20 years and get calibrated once / year, and work like a dream… my point is, do not expect a long laboratory life from a cheap balance.
It is like buying an IKA stirrer for 1K or one on ebay for 100$… 1K goes a long way….. 100$, well I tried and I got what I paid for, witch is fine…

@Max I feel like making a video on how to make your own stirrers! $1000 is wel over priced
The industry sells things for expensive due to the low levels of sales, it’s not mass produce

I’ll give a short overview,
There’s a motor ($100), you can connect it to a pole - that’s stainless steel worth $10 at best grade - by using a motor shaft couple ($4) or a drill chuck
You can buy blades that cut and metals never mind mix liquids for $5 lab size..
You need a tap and die set to connect the blade to the pole
