If you set aside the fact all statue prices have gone insane the last 3 years or so....
Tweeterhead is selling 1:6 statues for $270-$300 and I don't see many complaints about price over there, so I don't see a $400 price tag for a 1:5 statue that is very detailed unreasonable... Especially given SS is charging $550-$700 for 1:4 PF's..
I do see an argument for SS prices given the random QC you get with their statues..
