Yah, I also don't like fixing nose-pads on plastic frames. There are original plastic frames with thicker nose pads for asians. Those with thin nose pads are caucasian models.
I think Yellows Plus have metal frames, but most I've seen are mixed - acetate/celluloid + metal.
I'm a plastic frame junkie.

So far, I think designer frames from Vicktor & Rolf are pretty well done. The Japanese-made Paul Smith are very nice too. Recently, I found a pair of asian custom fit Oliver Goldsmith Vice Consul in their main shop in London Notting Hill!
Kame ManNen (Japanese) make excellent frames. Vintage styles. I have 3, a full titanium saddle-bridge model and 2 same acetate models in different colours. The titanium has been serving me since 2003, and I reckon it can go another 10 years (at least)!
LaFont is nice too, but I'm not sure if they have asian fit for plastic models. Metal wise, I think they are very nice. Their shop in Paris is quite a gem.
Do take note that weight is not on my agenda. Of course, common sense lah, if a frame is not your size, or too heavy for your liking, don't force yourself lah!
