Both in excellent condition. the 650T has Garmin NZ/Aus Topo's v4 installed. Both have the even better NZ Open Source Topo from Mr Purple.
Personally, the I always use Mr Purples Open Source Topo maps as I think they are better than Garmins maps.
The Montana 650 comes with 2 x rechargeable batteries and I'm looking for $399
The Oregon 450 is $299 and both include postage to anywhere in NZ.
Reason for selling, ahh, I've got too many and have upgraded to the Oregon 650
Note: There is no charge in any way shape or form for the Open Source Topo's included. Updates can be downloaded from this thread http://www.gwprojects.org/forum/viewtopic.php?f=17&t=1561
