Netfi, is there a practical reason you "need" a gi that has absolutely no brand markings at all? I understand wanting something understated, but every manufacturer these days has at least some embroidered logo somewhere.
Fuji gis are pretty bare, relatively inexpensive and high quality. HCK gis are also good quality for a solid price but not overly covered in logos.
Those gis on ebay are not near the same quality of the Fuji and HCK single weaves which are not much more expensive (Fuji single weave in white is 70$. )
I can understand not wanting tons of patches or logos, but if you want a quality gi you're probably going to have to compromise and deal with an embroidered logo somewhere on the gi.
