I second Cathay Photo, which is Singapore's largest photo store.
There are two outlets, one at Peninsular Plaza, the other at Marina
Square. Check out the website at
http://www.cathayphoto.com.sg/ .
I was there this afternoon and heard that new stocks for D70 are
arriving this Friday. I'll suggest that you get an I-quotation
before you come to Singapore. If the price is good (S$2100 appears
to be the standard price), you may want to ask them to reserve a
unit for you.
Another shop with a website is TK Foto Technic at shaw Towers.

Again, get an E-quotation for the best rates. The level of service
is quite good.
John 3:16 at Funan is not bad, but the small shop tends to get
crowded after office hours and on Saturdays. It does not open on
Sundays. The prices are in general slightly higher than Cathay
Photo's, though for the D70, it may be the same. MS Color at Ang Mo
Kio
http://www.mscolor.com.sg/profile.htm offers pretty competitive
rates but it's a little less convenient to get to.
I would give the shops in Orchard Road (especially Lucky Plaza) and
Sim Lim Square a wide berth. Alan Photo is at Sim Lim Square, and
Henry Goh recommends that place, as do some other local
photographers and enthusiasts. Unfortunately, I've read that only
one person at Alan Photo provides consistently good service and
quotes a good price. This may be true, it may not be. I've never
had good experience at that shop, but it could be the
'hey-come-rip-me-off, I'm-a-young-female-photographer face'. LOL.
You might have better luck there!
