Honestly, 20,000% markup doesn't seem that unethical at all. My sup HQ q250 amp with 96/97 in ele stats will only sell for about 170,000 dappers at 9999%. Most HQ q250 97%-ish+ amps should have a fair dapper value over 700,000 (about 41,000% markup)... Although the factor that limits the value of the resale most seems to be the low base prices calculated by the merchants.
