It took me a few weeks to receive an Orion 2" Deluxe barlow from them. I was a bit annoyed at them as they have it advertised on their web site, but when I phoned Sydney, they said they "didn't stock it" and "hardly anyone askes for it".
They had to back-order it. Luckily it arrived here yesterday (a Christmas present from me to me
, along with a 13mm Stratus)
