Don't expect anything good in Nokia Phones under 12 k Range. Between 8k-10.5k is mainly flooded with good phones like Motorola V3i, SE K750i, SE W550i, SE W300i, SE Z550i, Sanmsung X700 etc.
If you want something in series 40 then get the 6131(Flip) or 6230i ... for series60 (symbian) get the 6681/6630 or the 3230(FM), these should be around your budget
