Book1s 20-30k
Book2s 30-40k
Book3s 35-50k
Book4s 35-50k
Of course you got the normal extremes. I seen book1 for 10k b4. Book2s for 20s, book3 and 4s in upper 20s-lower 30s. I seen book1s for 35-50k, Book2s up to 60k, Book3s and 4s for 60-80k before. But the mean average price falls into that range.
