I've seen a NIB Nexstar on ebay for $300 when I was looking.. But
even though I never had a problem on ebay, you know you have to be
careful... I think I recently just saw one for $350 on ebay..
Though I never owned a Nexstar, And per say I'm not bashing it.. but the
two I have seen at our field, One by a old timer and the other a newbie
both removed the wing things

and shut-off the AFS and liked the plane
a lot better after that... That's things paid for, and you don't get the use
out of it... Your money, Your choice..
I did fly the old timers Nexstar with the AFS on low setting and off...
I'd take my Avistar any day....
