Back on topic for a minute:
I don't have Indiginus Renegade, but I do have several other Indiginus libraries and have to say they are incredible value for money - they are worth so much more than their price point, and I think most other developers wouldn't offer similar quality at their prices even during a Black Friday sale.
And regarding that other topic... sample libraries are toys. If you're serious you should learn to play guitar, drums, violin, cello, harp, bassoon, mandolin, banjo, accordion, pipe organ, synthesiser, oud, djembe and shakuhachi. You should also own your own Steinway D, Stradivarius violin, Neumann microphones, SSL mixing desk, and recording studio decked out wall to wall in Brazilian Rosewood... and you should keep Eddie Kramer on hand for the moments when inspiration strikes and you have to get it down on tape.
Edit... okay no longer being cheeky. I think a lot comes down to what you are trying to achieve with a guitar sample library - they could easily do a good job with things like arpeggiated chords, simple melodic leads, backing chord strums that are buried in the mix (some much more convincing than others), power chord riffing, Yngwie Malmsteen style arpeggios, Eddie Van Halen style tapping or dick dale style tremolo picked surf guitar playing, there's lots of ground the better libraries can easily cover. But playing something up front and centre that uses a lot of expressive techniques like slides or bends like Mark Knopfler or Jimi Hendrix might play is much less likely to sound convincing. Of course, if you don't know anything about guitar voicings, open strings and fretted strings etc it can easily end up sounding more like a harpsichord or Clavinet.
Edit 2: I don't think you need to learn to play guitar to achieve this - just buy a few guitar magazines with transcriptions (not guitar world - they ditched standard music notation a long time ago) and learn to play a dozen or so guitar parts on keyboard, paying attention to when strings are open (indicated by a 0 on the tab lines) as these will often ring longer, or when other techniques are used (eg alternative tunings, hammer-ons, pull-offs, slides, bends, harmonics, palm mutes etc). You'd soon get a feel for how these parts are best voiced on a keyboard.
