First decide whether you want a cruiser or a sports bike cause there is a world of difference between and they are designed to appeal for different kinds of riders. Cruisers are designed for a relaxed style of riding. They have large comfortable seats which can pamper your backside even on very long rides. They have a comfortable seat-footpeg-handlebar position which allows for stress free riding. They usually have powerful engines. They don't usually like corners and spirited handling and instead prefer straight highways. They can be a bit handful in city traffic because of their weight and length. They do have excellent ride quality though. If all this appeals to you then get the Bajaj Avenger which is the best cruiser you can get. There are the Royal Enfield Bullets but I personally don't like them. There is a new 200 cc version of Avenger available which a nice retro looking windscreen and a useful fuel guage missing on the earlier version.
Sports bike usually are designed for a sporty riding style. They have low handle bars and the footpegs are positioned slightly behind than usual. This makes the rider lean on the bike. This position is sporty but can be painful over long rides. They also have powerful engines with very nice exhaust notes. Their handling is much sharper but ride quality is usually sacrificed to achieve this. If all this turns you on then you should go for Bajaj Pulsar 200. It is one of the best bikes you can get for your money in India. Excellent performance, handling, ride quality and fantastic looks. Plus there is stuff like digital speedometer, led tail lights, alloy wheels, disc brake, etc. Its really popular here now. You're also familiar with the Pulsar so you'll feel at home on it, although i must say it is quite a different beast than the one you had.
So choose wisely.
