Original smoked ones are difficult to come by locally. However a new set can be bought off eBay for about 1.5k, and yes, they're gorgeous.
Similar to LED lights, not many E30 enthusiasts can accept fibre bodykits. There are still plenty of original bodykits available. If iX is your fancy, already mentioned that i have a spare set.
