I think if you ask around, most will recommend forgetting about an RTF or ARF... you save money by getting a kit, and you gain valuable knowledge about your heli by building it. When you crash, or have problems, you'll be able to easily troubleshoot and rebuild your heli if you built it from a kit. If you get an RTF, you won't have a clue where to start. I've seen guys with ARFs have simple problems and be clueless as to how to fix them, and I've had a few problems myself, and have been able to diagnose them and fix them very quickly (I built mine).

Heli suggestions (in preference & price order):
