I have just ordered some of these Sungpunet 7075 Aluminium alloy tent stakes, via Aliexpress.

Size: 18 cm length
Weight: 12 grams
Specs: 7075 Aluminium alloy
Price: US $12.58 for pack of 12 stakes (including shipping)
I believe they are somewhat similar to the MSR Groundhogs.
I'll report back on how they perform.
