I agree with beauxgoris that if you can get your hands on a GGH black city you should as it'll be so rare as it's discontinued. However, I don't necessarily think that RH is the best option for a newbie. You should go for something interesting and then you can come back to RH black when you're a seasoned collector. You'll love the giant hardware, it's such a fun lookGGH is dis-continued for SS 09 (at least at last update it was). So if you have a line on one and you want one then go for it.
I think a a Black city with RH is classic and timeless and always the best bet for a 1st b-bag imo.
