i agree...rose wines fly off the shelves in more established wine drinking countries during the summer, because they are the perfect drink on a hot day. theoretically this should make sense in SG since its hot most of the time (except these past few days), but our wine culture is still very new and most people view red wines as more 'premium' then 'whites' then 'sweets' and 'rose', in general.
i drank a new world Rose a couple of months back and I wrote about it in this thread. Very good and in a dry style as well, from the Barossa valley. Made from a blend of 4 grapes, including an italian grape. Here's the tasting note:

you can find it at 1885 Bottle Shop in Triple One Somerset. Very worth the price in the low 30s region (or was it $29?). Blends a new world style with old world sensibility.
as for old world style, the one i had that i liked a lot was Chateau de Roquefort "Corail" Rose from Provence. you can buy it from
www.wines2u.com.sg. THe prices listed on their site already include delivery charges so its very convenient. here's the tasting note (mines somewhere in the middle):

Wine Connections brings in some Provencal rose, although i've never tried them. Le Benaton sometimes carries in some Provencal rose as well, so it's worth a visit.
