Hello, I need an interposer with the minimal possible footprint, ideally it should have the same size as a FBGA-153 eMMC chip (11.5x13.0 mm). I've found three suitable models so far: Advanced Interconnections BGA socket adapter (price unknown, "please contact for a quote"); Samtec "Z-Ray" (same "please contact") and Ironwood "Grypper" ($709/piece).
Did you use any of these and could recommend any? Does Advanced or Samtec accept small orders (<=5 pieces)?
Do other eMMC interposers exist? Preferrably with a lower price, few hundred bucks is OK but $700/piece is just way too much.
Thanks in advance.

Update, in case anyone interested.
I have also found a manufacturer of cheap interposers in China, just $600/piece with a minimal order quantity of just 1 piece, search for "Sireda Tech BGA socket" (not advertisement). Their interposers would be the best choice in terms of price and usability, unfortunately those models are not suitable for my particular PCB as I have high profile components close to the eMMC chip.
As for the other manufacturers,
> Advanced Interconnections BGA socket adapter
- appeared not suitable for my project; did not ask for the price.
> Ironwood "Grypper"
- appeared most suitable for my project, unfortunately the price is quite painful for a small startup - the minimal order quantity is 4 pieces so prepare to pay ~3000 USD.
> Samtec "Z-Ray"
- did not contact them as I've decided to go with the "Grypper"
