Yeah, I got it last month after being blown away by the trial demo. If you order V1.5 before Music Lab releases V2 (they say Nov.) you can get the upgrade for free.
I think maybe the steel strings are a little better than the nylon, but I'm qubbling. RG is 8 great guitars. Haven't tried the patterns, I just keep it in "solo" mode and play notes and chords on the midi controller,running either as a VST through Sonar, or in stand-alone.
They say 2.0 will have a legato slide that will span any two notes you play, and I'm wondering whether that will be able to be used to render some facsimilie of a Dobro or pedal steel. I kind of doubt it, but we'll see.
This has become my "go to" acoustic guitar, and I can't reccomend it highly enough.
