REAPER.

It has a free 60-day trial. Full purchase is USD60 for personal use.

For fun, haha!

But seriously, just recording guitars and mixing. I write in Guitar Pro, then export the tracks as MIDI into Reaper. I use VSTs for keyboards, bass, and drums. I do the humanizing (velocity+timing) in the Reaper MIDI interface (kinda tedious, but there's some basic automation for it).

I use free VSTs for keyboard and bass (VST4Free). Honestly, they're not great, but they're free. For drums I use EZ Drummer (EZDrummer 2). Not free, but sometimes Toontrack has pretty good discounts during sales.

I've used Reaper for less than a year. The learning curve is a bit steep for me, but if you're familiar with a full DAW, then it shouldn't be too difficult.

Oh yeah, supposedly if you keep generating new email accounts to register in the Reaper website, you can keep downloading the free 60-day trial...
