Home Depot has a great tool combo set for about $299. Its a pancake compressor, hose, and nail gun that only shoots brads. The brad max lenght is 1 1/4 inch long.
If you need longer and a true finish nailer, I would steer you to the compressor less and hose less Paslode finish nail gun. I have the framing version and I love the idea of no hose and no compressor and light weight. It has its own battery, its own fuel cell and mag for nails clips.
You can buy a no mar attachment that treats the wood with care.
