I have a JVC 29" CRT, and totally satisfied with the performance. If you are in Mumbai, check out Vijay Sales outlets; they have good discounts running on Sundays. Also people swear by Panasonic but the 29" is hard to find.
If you are going to watch cable and occasional movies on DVD, then CRT is a good and affordable option. If your usage is veering towards movies and less of cable then an LCD will make more sense.
Also CRT's are going for great prices nowadays since they are on their way out, and your budget of 15-25 K is actually too high for a CRT but probably less for an LCD. Search for a Sony WEGA 29 if they are still available since Sony has stopped manufacturing CRT's. I had seen one at Vijay Sales some time back going for 18K.
