Roland VG8 Guitar system?

[Legion <Legion@voicenet.com>]

I've got a line on a used Roland VG8 guitar system (Floor unit, GK2a
pick, cable, etc).  I'm only passingly familiar with this unit so I'd
like to get actual users feelings on how well it tracks, how flexible
the sounds are, how it compares to the other GR1/9/30 series, etc.
Basically any info from someone who has used one for a while.

Does it have built in effects? To be on topic, can it Loop? :)

Finally what's a fair price for such a unit these days? I know they were
pretty darn expensive new if I recall correctly.

Email privately if you feel it's more appropriate.

Thanks for any/all help
