I also notice Megrez 110ED. It seems a better choice for the size/weight and its price is very good. Takahashi FSQ106ED however is over-budget for me.
Thanks all for good advises.
You should see the scopes in person. I was quite surprised with the size of 110ED when I saw it at CC's house. I think the largest airline carry-on refractor (i.e. case cannot exceed 22", total weight scope and case cannot exceed 7kg) is WO Megrez 90mm, unless you can afford a $7k AP traveler
there's always the borg 125 for people with deep pockets. i almost got my hands on one of those 125ed. megrez 110 prolly is a nice size. megrez 90 is another nice size for a grab and go.
