ok, I admit it is not the cheapest one you can get, but also not the most expensive one you can get either... I went for quality and very good insulation: this reduces heating costs and is cheaper on a long term...
my money tree... yes, I have one, a very strong one which I have been caring of very carefully since at least 20 years.. here the recipe: work hard for your education (don't need to go to the best University for it.. it's you and not the university that must be good!), work hard and be honest when getting the right job, work hard and with open cards in your job, take care of your career and career plan... and very important, do not neglect your life, friends and family (these are the ones helping you with the hard work, if,like me, you get sick in the middle ofthe work

) on the way... as simple as that!
