Well said Peter.
The RCOS are expensive, however they represent a whole new level of control and monitoring over the telescope system. The cost of all the electronic extras is half the reason they are so damned expensive, although to some users who are setting up remote observatories, these are requirements. The RCOS scopes fully optioned are an unparalleled imaging platform..
The GSO is a very nice compromise for those of us who dont require ion milled optics, temperature controlled focus or telescope command center.. (I wouldnt mind a RCOS instrument rotator though!!
