regardless of how much they cost when new their value is what people are willing to pay for them. just like the house your parents bought 30 years ago for £18k is now worth £100k. No one moans about that.
At the end of the day a PT isn't essential. It's a luxury. A connivence thing. Sure it's annoying the price keeps going up. Personally I paid £62 for mine and I don't regret the purchase 1 bit. It's probably the best thing I've ever bought RC wise.
If you don't like the price use handouts. Or buy one and think what a godsend it is.
