The hard part is finding someone who is willing to help you out with the trade.
that's mostly because the ratios posted here are way off.
it's easy to get 100-120k for a 240kAP item using guidl stores. sure, you end up payig the store fee, but in the end, the ratio is closer to 1:2 than 1:3. Anything like 1:5 mentioned here is just the gold guy making a great deal off some PvPer who doesn't care about his earnings. You'll need time to find someone liek that.
Sure, AP is inflationary, but gold is even worse.
