Many thanks for the kind welcome
Iceman - I found the site a while back via google while looking for some reviews on the GSO dobs as I'm in the market for a cheapie for my niece.
jjjnettie - Generally speaking I use which ever is most appropriate for the seeing conditions on a given night and my observing target list. The least used as a stand-alone telescope is the TAL as that normally rides on the 16" as a guidescope. The 8" F8.7 probably sees the least use at present as it's a beast, the OTA alone weighs in at over 40kg., however it's brilliant in windy conditons, which are all too common here in Perth.
