My first reaction is the well reasoned logic that a grow is an investment - you invested in lights, tent etc etc etc and theres running costs like electricity. If its legal in your area, your also risking a fine or the financial impact of losing your liberty. SO, convention says, don't waste it on unknown, unreliable genetics. Even if you bought the most expensive seeds, its still only a small fraction of the total cost of an indoor grow.
Also, the genetics you get for your money could be with you forever, long after the equipment was replaced 3 times over. Me and my friends kept a clone going for 30 years cos she was so lovely.
BUT my final thought.. - A lot the legendary clone only elites are either bag seed or a cross of bagseed...so
