Hi! Looking for a suggestion on where to source inexpensive microSD sockets (SMD) that also have Eagle library (since I'll be making custom PCB). Preferably under $0.50 
I've seen some on eBay for $2.50 in 10 pack, but they don't have Eagle library and I'm wary of incorrect Datasheet image they have in those auctions (learned hard way that many of them simply have wrong dimensions)...
Are you buying in large quantity? DigiKey has plenty of choices but if you want to buy in Quantity 1 you have to pay $1.11 each. The ones that cost less than $0.50 have a minimum order quantity of 2400 or more. There is one you can get with a minimum order quantity of 800 but they cost $0.60708 each.

No, not that large
Maybe 50 max
Oh and I forgot to mention, I'd like those that are easier to solder. I think I can go as high as $1.50 each if it's both easy to solder and have Eagle library I have zero experience with microSD cards, so any suggestion will be appreciated
P.S. Found this one on mouser. Seems easy to solder, not too pricey. Anyone has Eagle library for it?

Define easy. I bought some good quality ones from eBay cheap and they are perfectly easy to solder - the pins are exposed and not under the socket or anything like that. I had to make my own pattern but it works just fine. You give it a shot, print it out, see what lines up and what doesn't. Once I had the PCB made it was exactly as expected. I use DipTrace though, not Eagle.

I think that would work, thanks! Yeah I meant pins exposed outside. Pattern looks pretty simple, I think I can figure out.
BTW I just spent 1.5hrs trying to draw that DM3CS-SF part from their datasheet, it's a freaking nightmare :0 I can't tell where ground pins are, that drawing is pretty bad or I don't know how to read it.
I use the ones from dipmicro on the vinciDuino evo uSD an the are working great. Very easy to solder too. The ones from eBay look as if they could be fitted on the footprint.
I use the library published by crossroads with a minor mod to align well the pads, even though it will work as is.
That's a great idea about using existing library and realigning that doesn't match! I tried to make another library from scratch and just gave up
But those Dipmicro sockets are really possible to solder with regular solder iron? From picture on their site it looks like they have pins under socket?
Yes, they are indeed hand solderable. The pins are at the back, not underneath.
They are very easy to solder. The pins a very accessible as Crossroads points out and with a large separation in between. I solder them by hand and I am not an expert. A bit of flux and voila.
If you click on the picture of my web here: http://www.electrofunltd.com/2013/01/vinciduino-evo-usd.html you will see the solder work. All done by hand and a $80 Chinnese solder iron.
Awesome!!! Thank you CrossRoads and fm! I didn't realize picture was from the bottom. Just ordered mine.

I wonder if anyone knows the part number for this style of module from some reputable distributor like digikey or mouser?
I have originally found this module as ST-TF-003A on seeedstudio open Open parts library and I was going to give up but now I have hopes for it since it it so widely available from eBay. Still, want a major part no. to feel better
Try this.
