Best Investments
I think the best investments I have made in the recent times have been the Washing Machine, the Reverse Osmosis System and the Refrigerator.
Car was a bad investment overall but it made life a whole lot convenient. The LCD Monitor I bought made working a bit more comfortable. The Dish TV made it possible for me to watch a bit more of television (which has really become THE IDIOT BOX).
The super expensive camera does come handy at times. Other than that I do not think I have made any investments (in stuff) that I think were worth making!
Update: Forgot mentioning the Air Conditioner and the 2 UPS Systems… I guess the next major investment I would be making would be for an Online UPS.
