I have a Laney 2x12 cab I bought years ago, and I don't ever see myself getting rid of it. I did replace the stock speakers, and it sounds even better (at least to me). I've owned several other 2x12s, but it's definitely my favorite.
You should be able to get Garage Band for free. It's an app you can download from iTunes.
I don't own a Mac, but Garage Band is supposed to be decent, so it would probably work for what you want to use it for.
@matthew bear I don't blame you. I've had the XL+ for 4 years now, and haven't seriously looked at anything else until the FM3 was announced, and I saw how compact it was.
HX Stomp would be my other choice, but FM3 feels like a no brainer for the features and price point.
If I didn't like Fractal so much, I'd honestly go with a Helix.
This will be downsizing for me, as it'll free up a ton of space in my super crowded room. I'm sure my XL+ will garner some interest from someone.
