Yes we do love our Customline SN, sorry tend to rave on a bit about how good it is.
I would definately look before buying second hand. Try putting wanted ads on Myswag.org, Campertrailers.org, Gumtree.com.au, 4x4 forums and of course here also put watches on ebay,ozation,rvpoint, trading post and any other sites that sell second hand CTs.
Have found though that CT's are tending to hold their value and are selling for not much less than they were bought for except for ones that are a bit older.
Good luck with your search it's not an easy decisions with sooooo many choices out there it tends to swamp you a bit. Keep us all updated with how it's all going.
