Whoever opens up services initially after the servers come online would be generating large amounts of revenue and the price would be relatively high.
In my opinion, the best action to take would be level yourself until you reach most requirements, wait for gold prices to stabalise then look into purchasing services.
Since there will be close to no economy, and the revival of BANK SALES it will be very difficult to get items and so on.
But on a side note, the removal of GE means an increased need for the Item Sales section here on Sythe since they can use Sythe as a median to buy/sell certain items post 07 release.
