Following a proposal, let's have a thread to post and discuss various interesting deals on interesting memory.
My own contribution will be (hopefully) frequent lists of ebay items ending within 2-3 days that I personally find interesting.
Don't hit me too hard if I get some ICs wrong as obscure makers/models can be inconsistent and ebay pictures/descriptions can be wrong.
Also note that low-binned stuff is not guaranteed to clock well even if it has "good ICs", but it can be interesting for those with a tight budget.

So here goes ...
