I cant comment on the 13x80, but I picked up a 9x50 from IceTrades a little while ago, absolutely love it!! Nice contrast, pinpoint stars and pretty handy for checking out big open clusters...
The Helical focuser doesn't have any way to lock though, so tends to go out of focus if you happen to bump it. Is also recommend picking up an illuminator, the crosshairs can be a bit difficult to see otherwise.
Hope it helps,
Davin
