[slice of heaven]

Just ordered the12" gso from Andrews .What I need to know is;
Is there any benefit in a 2" barlow over a 1.25" barlow?
My old scope has a 1.25" focusser,(rack&pinion,smooth,no slop so I've no mind to change it) so if I go 1.25" I can use it in both .
But if the 2" has some benefit I'd consider that for just the gso. Both scopes are basically the same specs.The gso is more for the kids (yep kids like big buckets too) but being lighter I can see myself grabbing this one for the late night ,on my own viewing.
Also,opinions on a value for money barlow between $100-$200
would be appreciated.

Thanks,Geoff
