I think there is a lot of emphasis on the term "investment," but I'd like to clarify that point. Any major purchase is an investment whether you are a professional or home noodler like me. For those of us who don't have the money to burn, $1500 in a modeler would be a major disappointment when version 2.0 comes around. I suppose it depends on how well the company supports the old product. I actually don't know if Fractal, Kemper, or Line6 do a good job of supporting old models. If they're anything like Microsoft, then good luck with that! When it comes to repairs, at least most tube amps can be fixed after warranty expires. With Modelers, you have to wonder what you would do with a $1500 Helix that dies a couple of years later. It would seem as pointless as repairing the circuitboard of a computers video card instead of replacing the card because it seems like finding a qualified tech would be much harder, and troubleshooting and repairing complex circuitry seems very expensive. It's probably not like repairing a VCR. However, I really don't know much about these specifics so I'd like to learn more in those aspects.
Anyawy, I do see the benefit of an AxeFX or Kemper and will probably get one soon. I wasn't always like that before, but using a Zerrer for a while for practice and recording through my audio interface, I realize what a great asset a quality modeler can be. Not that the Zerrer is a modeler, but for my uses, an AxeFX would be super cool. Five years ago, I didn't think they sounded all that great, but from what I've tried out lately, they seem to have raised the bar.
