A place not to do this is with R/C helicopters. Best to buy them from Brookstone with the 1-year no-questions-asked warranty -- you WILL destroy them and you can go through your 3-6 choppers for the price of one.
Nice tip. I've always wanted to get one of the R/C helicopters and was always planning on getting it from one of the aisle mall shops - but this advice is helpful.
Like with the cables, neither makes sense. I could just buy one cheap cable from a reputable brand and probably not need another for 30 years.
And if I do? I'll just buy another. Because they're cheap and work perfectly.
