It depends on the materials you will be drilling, and the frequency that the drills will be used. Unless you are planning to drill stainless and alloy metals, the TiN (and other coated) bits are an expensive luxury, costing double to triple. For around the house and general hobby use, polished finish, split point drill bits will suffice. For better wear resistance, you may wish to consider cobalt drill bits; more costly than plain high speed steel, but cheaper than coated bits. The only coated tools I use are milling cutters because they take a beating and are expensive to replace, so the coatings pay for themselves. Check out MSC Industrial and McMaster Carr for what is available and pricing. They both carry top brands. Of course if Santa Claus has extremely deep pockets, than coated carbide would be the ultimate.
