The C427 is a great tuner but is very expensive as it has the RDS and RT facility (Radio Data System is for passing digital info like station name, song name, genera program info, etc while RT is Radio Text is used by stations for passing text messages like slogans, important announcements, etc), has 40 odd presets and works with any standard full-function NAD remote control. Now, if you really must have it and can afford it, then 50k is the price to pay. However the reality is that RDS and RT facilities are of no use in India and at the end of the day, you are going to have to listen to our regular Delhi FM stations. Hence 40 presets are not going to be of any use either. Yes, the remote is handy though and one advantage you have is that you can mix AM and FM stations across these 40 presets. The older NAD tuners would had a separate set of presets for AM and FM and hence, you'd have to switch between AM and FM to access your AM and FM presets.
This tuner is great to have as it is modern and claims to have a great front end, so you'd essentially get good reception with high quality sound. Having said that, 2 NAD tuners from the past, considered to be arguably the best from NAD, can compete, if not beat it. These are the NAD 402 and its sibling the NAD 412. You can pick one of these up for between Rs.2000 and Rs.6000 depending on the condition and enjoy great NAD reception and and audio quality with the same features like 'blend' which is used for playing stereo music in when the FM station is weak. The number of presets are 12 for FM and 12 for AM and they dont have remotes. But you can enjoy the NAD tuner experience to the fullest.
If you still want to be contemporary, why not try out the C426. It is also a RDS/RT tuner but with 30 presets. The C420 is also not bad.
