No please leave it like this!!!
IT acts as a filter just do not buy the overpriced items !! the price is exactly what identifies them !!
If they all become the same range it will be harder for you to separate the wheat from the chaff !
And then you have to buy&try even MORE trust me.
I think Metaquotes should set price to $20 per item and make developers cover all losses that buyer eventually makes by using the product.
And, of course, to qualify for the market, a product must have at least 100% profit per month on the live account, not smaller than 1 million in some hard currency (USD, EUR).
That way we will all get rich, not only dirty, rotten developers who are selling overpriced products and ripping people off.
