Smile G-11 Goto Gemeni vs Argo Navis

I have finally battered the 'Minister for War and Home Affairs' into submission, and have been given the go-ahead to procure a Losmandy G-11.

I note that Losmandy offer the Gemeni goto system at an additional $1500-ish. In the blurb, it is stated that with this upgrade, the standard stepping motors are replaced with a constant drive system, hence a smoother drive due to less stepping action.

Speaking with Gary Kopff at the Border Star Gaze last weekend, he advises that there is a kit made by Losmandy to fit his Argo Navis system and use it as the goto. This path would save approx $500, and the Argo Handbox could be used on other scopes when not required on the G-11.

I wish to use the G-11 for astrophotography - with a TV Genesis refractor.

Does anybody have any experience with the Argo Navis on a G-11?

Comments on tracking/guiding with the standard stepper motors vs the constant drive would also be appreciated.
