I very recently added a 10" Dob to supliment my Celestron Nextar GT. I went looking at what was available (2 shops I could find on the Gold Coast) and I ended up finding that the price difference between 8 and 10 a couple hundred, but upgrading to 12" was just over double the cost of the 10". I was assured I would not grow out of my 10", and I must say the clarity is every bit as good as I was told. I picked up a brand new 10" Dob for $550. I thought that quite well priced? The 12" was $1200. Seemed a hefty upgrade as opposed to 8-10. The Meade eyepice kit was as much as the Dob though. The wide field peices are a real treat. I thought that better value than the larger mirror. Weight is something too, it's qute a beast to even lug into the backyard, but I find well worth the effort.
