Cheapest BTC miner for learning?

[Abiky]

I am going need some recommendations regarding looking a cheap BTC miner with the purpose to teach others about the process of mining. I don't really need one to profit from it (no matter if it has a very low hashrate) just want one for educational purposes and use it as a medium to promote Bitcoins too. Any ideas on what type of miner would be the one suitable for this task? The cheaper it is the better.

The good cheap miners would be an antminer U3 or U2.

The U3 is at around 60GHs so not that big and is around $20-30
The U2 seems to be around 2GHs.

I think the U3 is also only a few hundred grams.

Potential: you could also get an antrouter R1 and smash it to view its components for educational purposes, as a miner it probably isn't good but is small.

EDIT: their price has increased so this may be better:
GekkoScience Compac 8-16 GH/s (23 GH/s max.)

Otherwise, if you want a standalone aio miner use an antminer s1 or s2

Great! Thanks for sharing these miner recommendations. The ones that I liked the most were the Antrouter R1 and the GekkoScience miner. I will give these a shot and educate myself as well with it. For testing purposes, how do I actually mine testnet Bitcoins with it? Is it really possible?

Get yourself a nice usb powered hub, and a RPI as a controller.  Then by some GekkoScience compacs. They simply  are best BTC mining usb sticks right now.  For learning this route is very good.

Only thing you need to be aware that chances of ROI are pretty much none unless you sell it someday and made  money on sale.

Thank you for your reply. All I need to do right now is buy a GekkoScience miner and a usb powered hub. I have a spare RPi lying around so this shouldn't be a problem. These will make a great tool for educational purposes. If I then decide to sell them, I would do so by listing it at a price a little bit higher than what I have bought them in order to ROI. But that would be very unlikely since I will keep them for time sake.

I should mention there is no guarantee with ROI.  Sidehack is making a pretty sizable 2nd batch of compacs.  So there are more on market, you might not be able to sell for higher... and you might be able to hard to say.

I know i sold some of mine when he was out and it worked out great as people wanted a product that was between production runs.  Not all will get this lucky.
