Takahashi TSA102S F8 @ 816mm Triplet Super Apochromat in mint condition ... ( I know I will regret this, but......
)
The TSA102S is the finest 4" scope I have ever used. This one is in superb condition with only a few dust specks on the objective. Mechanically and cosmetically excellent +++.
Update:
Thanks Andrew, what you said is quite true, " where would I ever find another in this condition"
I will tell my wife to blame you for the clutter in the office 
and keep the TSA.....
