I have to say I'm actually not certain if I'd sell the VC200L off either. The local shop offered me approx $250 for it. It's probably not worth it to sell it off at that price however storage space may be a concern.
I went to Starbase in Akihabara and saw the TOA-150, TOA-130, & TSA-120 and size-wise the TSA-120 would have been perfect. However some of the advice I've had about the moving from an 8" RC variant to a refractor of 120mm would be comparable (I believe the general guideline is diameter of the primary - the 2ndary obstruction?). So I'd have to look at the 130mm to consider it as an "upgrade".
The TOA-150 is massive. In fact I'm wondering if transporting and mounting the TOA-130 would be a difficult task or not too.
In the photo the front is the TSA-120, whilst middle is the TOA-150, and the tallest last one is the TOA-130.
