Which CHEAP cube in medium quantity (24-48 pieces)
Hi,
I want to have lot of cube so I can illustrate the different steps of a solve or a technic. I need at least 22 cubes (since all cubes can be solved in 20 moves

), and may be able to afford up to 48 (but really, I don't want to spend more money than necessary).
I won't use these cubes, and really don't want to (nor can) pay 24*$5 for them. On the orther hand, I want something that *can* be solved (not they 3cm keychain that are so hard that you break you nails trying any rotation).
So, the cubes I've eliminated for now are :
-The cheapest 30mm keychains like

-The cheapest 57mm cube with square angles like

-YJ Guanlong : this cube is very nice for the price, but best deal I could get was $69 pour 30 pieces, and though the deal is great, $69 is too much for me.
So, there seems to be a few alternatives, like
-"higher" grade keychains with rounded edges :

-These "magic cube" cubes don't look as bad as the cheapest ones, but I could not try them nor find any review :
http://www.aliexpress.com/item/Thir...oys-professional-magic-box-3/32527244557.html . I can buy 2 boxes (24 cubes) for $36 shipped. (I'd rather have black cubes but...

)
-The Cyclone Boys mini (40mm), cubezz sells them $31 for 22 pieces. The cube is not perfect (40mm, white, can't be tensionned) but usable.
Did someone test any of the two cubes I've found ? Does someone know of any alternative ?
Thanks you
