Cut the messing about and get the DP127 - you will not regret it I'm sure. They p155 rings around the SDs IMHO. If you've found them both about the same price it's no contest
Edit: Ki pronounced key is Japanese for Yellow and Ogon is a single coloured Koi, so simply 'Yellow Koi'.
I have kept Koi since about 1975, when they were very few and far between in this country and the Yamabuki name taken from the Flower in Japan '[i][b]Kerria japonica'[/b][/i] (abbreviated to Ki), has always been my personal favourite Koi, almost impossible to find a perfect example.
It's been my nickname for years and the reg. no. on my car; KI0GON
