Looking to improve preflop ranges, currently use modified snowie ranges for free.

Monkersolver/PIO ranges go for $500+.

Are they worth the investment?

Is there a better way to get these ranges?

For instance , you get ranges with the purchase of kanu7 cash course for 1k, making it a bargain, but not sure if these are good for blitz tables?

Any help appreciated, thanks in advance.
