OK, so I know there are a bunch of Yamaha RGX fans out there. [img]/images/graemlins/grin.gif[/img] What can you tell me about them? How do the neck thru models compare to early 90's MIJ Soloists & 650XLs or late 80's Model 6s? Also, what do these things go for these days (is ~$300 a good deal on an RGX1212A)?
