Just put the colour camera on a cheaper scope with a comparable focal length. 8"f/4 sucking down lum with something like an 80mm refractor on colour duties...

There is often a misconception that it is quicker to take colour data with a OSC - it is not. If you take 2 hours each of R - G - B with a mono then you need 6 hours data to get equivalent with a OSC.
I have used a dual setup for some time now - using a SBIG ST4000 XCM for RGB and a ST10XME for mono and narrowband - the system works very well - especially if you get limited imaging time.
