What a set of drool worthy images
Don't part with the VC200L - a fantastic scope, and easily still worth around $800 to $1200 2nd hand, in Aus at least.
If I was lucky enough to be in your shoes, I would go with the TSA120. Sure, the TOA's have the advantage of aperture, but at a cost to portability (heavy OTA's) and rely require a mount upgrade - the 150 needs a GOOD mount (not an NEQ6 or similar - something like a Tak NJP or EM400 upwards), the 130 not too much different. The TSA120 can ride a Vixen GPD2 by memory, for visual at least, and DEFINITELY an SXP for imaging.
Out of interest, what price was the TSA120? I might have to 2nd hand shop in Japan
