I'd just like to post a very big "Thumbs up" for Harrison Telescopes. After my smashing time with the wind and my AVX mount deciding that it needed to "positively uncouple" i.e. break in two, I rang round looking for parts or a scrap AVX. No luck with parts but when I rang Harrison Telescopes, Ed said that he'd got a complete mount except for handset which he'd let me have for a very, very good price. It arrived today and is exactly as he said, basically nearly new! Brilliant service and communication. Harrison 'scopes have a new and loyal customer. Highly recommended.
