Not a rose but if your taste runs to very sweet sugary wines, you will probably adore Fresita from Chile. A sparkling blend of chardonnay and sauvignon blended with strawberry puree. See: www.smithfieldwine.com
Personally, I wouldn't touch it.
actually it could be Rosemont. (Rougemont?) anyway it's cheapo red/rose from tesco - about a tenner for a 3 litre box and very sweet (very drinkable i might add)
In that case why are you stipulating rose wines? I would thoroughly recommend German whites - taste fantastic, they never go wrong, and are dirt cheap. Try Bernkastel or a Piesporter (the Hock is very sweet and very very cheap table wine). Personally i would recommend a Kendermanns Reisling which is fantastic served cold, but possibly a bit dry for you if you're after sweet wines.
Fetzer do an an amazing Syrah Rose. It's not sickly sweet (I'm a dry man myself), but it's very fruity, and not unlike Ribena. Go to Threshers and look for the Red-looking wine in the fridge.
