1) you should keep in mind that all machines work the same for a given amount of money. for a given price range, they give you the same value, no matter which brand they belong to. this is true for all the local brands to the exceptional ones likes Miele.
2) so, instead of asking for "which brand", you should ask/look for specific features you need. each poster will have a different opinion regarding a particular brand... and you won't reach a conclusion. please list what features you would like to use and maybe someone can post their views.
3) after sales service does not depend on the brand but the locality of the buyer. service providers know which machines don't like hilly weather and which don't like the corrosive seaside environment. so, you won't get same kind of services all over India. do a local market search and list down the manufacturers which provide services in Nahan.
4) there are pros and cons for both front and top loading machines. which one do you need?
