Another vote for Peter and SDM - I enjoy my 16" F4 built by him very much... I've seen more than a couple of Obsessions which he has rebuilt and upgraded.
As for how big is too big - I've been wrestling with this my question myself as I dream of the next big thing !!! Having looked through a range of 'big' scopes, the increase in performance becomes more and more subtle as the pain in the butt factor increases rapidly with size, weight and heigh. Also cooling is a huge issue if you live somewhere like Victoria with large day to night temp drops.
My heart would like a 30" F3.3 ... My head says 24" F4 or F3.3 with a 1.5" thick mirror is probably truthfully the sweet spot of easy of setup, movement and use.
