help required for choosing my dth

[aytus]

hi guys.,.even though the new offer from dishtv of free stb is tempting, i am thinking about buying Tata Sky bcos of the good reviews i read on this forum about its customer care. i have some queries.. and ill appriciate ur help if u take the pain to answer them. 1. im confused about how does the payment system work?? i mean suppose i want to see the tv for one month and maybe then for two to three months im out of house (gaps) and i dont want to pay.. can i do that. is it comparable to prepaid/postpaid mobile billing system??2. will i be able to view fta channels in the month in which im not paying in tatasky?? what about dish tv??3. suppose in case i want to change my service provider after say 1 year.. what will that leave me with. i suppose i own the stb in case of tata sky and the dish is on rent.. if i dont subscribe to them anymore after 1 year .. will they take the dish away?? and leave me only with the stb.??
