This amounts to like the base price of a cruiser (without fittings) or a decent skill book.. I think this is fair and should not rip a too deep hole into your purses. Looking at realworld isk-prices of about $10 per 100 mil, this is like about 2 dollars a year.

But before you commit yourself, you can try the full edition of eve commander for 14 days for free. After that period and if no payment has been made, your account is simply reduced to the limited edition of eve commander. There is no obligation and no automatic subscription whatsoever!

When you start with the limited edition, don't bother a thing: eve commander will always be free. And you can toggle to the full edition (and a 14 day trial from that time on) at any time.

Again for comparison (see the 'about' page for more information and screenshots):

Version	Features
limited edition	- general character information - skill training information - character overview page when registered with multiple accounts

* for a maximum time of three month after account creation. this, as free full edition is intended for new players and not characters keeping their cash in an alt or corporate account... :) 5 mil isk are charged for these chars.
** can only be ordered by the ceo or with the ceo's permission. this is a one time fee additional to each user's regular usage fee. contact me for details.
