A fifteen minute radius around Tai Po would also probably encompass Sha Tin and Fan Ling so you may want to narrow it down a bit.
You have a whole range of prices in the Tai Po area, ranging from very cheap in areas such as Tai Po Centre and UpTown Plaza (probably around 5-6k for a small two-bed).
Mid-range (includes clubhouse facilities) in places such as Classical Gardens, Paragon, Grand Palisades (anything from 8k for a two-bed 600sq ft place, to 12-15k for 3 beds 1000 sq ft).
Then onto the more expensive places such as developments on Tai Po Road south of Tai Po, and some places around HKIEd off Ting Kok Road in the north and Hong Lok Yuen in the west.
Village houses are everywhere. Best bet is either up near Plover Cove in Ting Kok Road. Very active place for restaurants. Lam Tsuen has 26 villages of varying sizes. And then the area around Yuen Leng and Tai Hang villages to the NW. Also south up into Wun Yiu - 10 villages and a few low rise developments of varying expense.
You could always move into JC Castle and have Bona Mugabe and her nice bodyguards as neighbours.
