I hate the Andrews Web site. It looks like it was designed in the 80s and has never been looked at by a competent Graphic designer. Impossiobe to find anything easily. No online purchasing, and a general attitude.
Bintel seem to always have to get what I want from back order. They seem to have very little in stock, and they have high delivery charges. Apart from that they seem ok
I prefer Sirius Optics, Optics Central and Ozscopes to either.
Oh and despite "quirky" web sites don't discount Sidereal Trading and Astroshop
Just my 2c
