Hey Dakka,
Long time lurker, first time poster. Here is a quick Cryptek conversion I did using only parts from a single Necron warrior,
GS, and a syringe needle (Where's a good source for ~<1mm Diameter rod?)
I am not very experienced with greenstuff and I find it difficult to work with. It feels like working with gum sometimes - good, sharp edges are pretty much impossible.
Crypteks, I imagine, are more like frail wizards and use a Warrior-sized frame (4+ save) rather than the bulkier frame the
GW model has. The deathmark head also bugs me.
Anyways, I hope you guys like the general idea - 10 crypteks for ~$35! I'll post a painted pic soon.
