This "simple" device has the hall mark of all good or great products in that you look at it and say "I could make that myself!!!" However, for the price and effort you would need it really does not seem worth it to do so.
When you also weigh it against the cost of half sliders that will run you $300 or more new and which still leave you with only a half window, it becomes a bargain that you simply can not pass up or would be silly to if you are entertaining that alternative.
