My install is on Sat. and I have a couple concerns: 1) Is this the best package availible: I got the Top 180 for 3 months free, $49.00 free installation credit and the DVR-522, free equipment. 2) Should I get the insurance? 3) What should do before install? 4) Is there I should ask the installer before or after he/she is done? 5) Do you tip installers? 6) Is the DVR-522 a good unit? Should I upgrade? Can I upgrade after instalition? 7) Can you pay a year in advance? Do you recieve a discount if you do? Would you recommend it? 8) What is CLUBDISH and how does it work? 9)I live in an apartment is ther anthing special I need to do ? 10) How is there customer service and repairs? Thank you everyone for any advice or suggesions you could provide!
