WTB: AC Adapter (2X) for T61

[asiafish]

Ideally I'd like a 72 or 90 watt, but it really doesn't matter as I already have a 56 Watt for travel.

I need two total, would buy three if the price was right.

Is there a way to tell what AC Adapters are for what thinkpads?

[asiafish]

The T60 introduced a new type with a larger round plug with a center post. This works on all ThinkPads since 2007 or so, while the older narrow plug without center post will work on most ThinkPads from 2006 or before, ending with the T43.

If the number on the ThinkPad (ie: T23, R52 is less than 60, it probably has the old style AC adapter, while a number of 60 or larger (ie: T61, R500, X200) indicates the new type.

Come on, doesn't ANYONE have an extra AC adapter they want to sell?
