After losing 200 perks resently due to disco I think that it is way too much for my ISP problems.
I also think that some planes are overprised.
My suggestions and resons for the price I suggest:
f4u-C for 8 perks is fine. It was my jabo plane of choice, and it really cost those perks. Now it a big more heavy, so I use tiffie more usual for jabo, but 8 still is ok.
Tempest is overprised. It's fast, has great guns, still not very good at alts, and not the best dogfighter. Though in this case I think it is overprised marginally, and it shall be around 50 perks.
f4u4 is overprised. Its a great plane, no doubt, but not close to its price. Main thing which justifies its as a high perk is that at the moment f4u4 is the best carrier based plane. I hope it will be priced down to 30 perks.
Arado is a great buff, almost untouchable if flown right (at least it was prior to 1.08). From the other hand it carries small bomb load and now it can be killed by me262. It shall be more cheap now, around 35-40 perks.
ta-152. 15-20 perks. If it had better climb rate I would use it as a high intercepter due to its speed and good punch, but practise shows that when you climb it high enough, it is already friendly 109g10 there which kill the buffs.
me262 price would be ok if not a disconnects problem. Last nigh one .303 ping of a lanc, which died 5 minutes prior to my disco cost me 100 more perks. Either this problem shall be somehow settled (for example if I pinged BUT still no dammage, high enough, enough fuel it shall be 100 perks lost) or price shall be put down. 200 perks for bad connect is a lot even if you spend many time in AH, and TOO DAMN MUCH when you fly hour or so per day. Again, this tends to grow to the most frustrating problem for me in AH, because I like me262, and going to use it.
Also, I think it is nothing bad if prices will be adjusted and then plane usage will be monitored in the end of tour. This way perk price system would not be so rigid and more adequate.
