$1300-1500 seems a bit high to me, but I am spoiled by great local PCA events that only cost me $100-200/ea.
I did do a Skip Barber "intro to racing" school at Lime Rock park about 5 years ago. It only cost about $700, was a 1/2 day thing but got to drive a Formula Dodge single seater - and given my physical size, nearly got to take it home with me as I struggled to get out
