Are they worth the $$
I have a 10" GSO Dob, which I believe uses the knobs made for 10" Meade Lightbridge.
Is it better to get knobs for both the primary and secondary mirrors?
Thanks

Liz, They are worthwhile, but I question how much dearer they really are here vs. buying them from the US. Your link shows them at $29.95 USD which at todays exchange rate, will cost you $37.60 AUD then shipping on top of that. BinTel (for example sell) them for $44.00. That's only $6.60 more. Not really "too dear in Aus". Ring BinTel for a price and ask their postage costs. I reckon at the end of the day you won't be saving much.
Good luck.
