I'm in the same boat, looking for a simple combo solution for times when taking my computer based setup would be a PITA. I have an Amplifi 150 here, and would love to make more use of it. I can't use it as an FRFR because the interface doesn't seem to work the way most other Line 6 products do, where you can run the USB interface inline and/or parallel with the amplifier's sound, you can only run it in parallel, so the actual amp path will always be in the signal path, useless as an all in one interface/FRFR.
I've been trying to find a way to wire a line out tap ffrom the speaker level wiring, but it seems too sketchy and chopping up what would otherwise be a perfectly serviceable unit.
The Spider 5 looks pretty cool, but for some reason they dumbed down the included FX from the Spider 4. So maybe a Spider 4? Seems to be a glaring hole in the market, if Line 6 would just stick the HD500X in a combo (and wish of all wishes, let us import our own IR's) that would murder the marketplace
We had a Firehawk 1500 here for a while, and it was OK, but for its size and cost, and the fact that the controller app is horrid and makes you relogin every 30 seconds, no thanks. I actually would have kept it if you could edit on the PC at the time (tried to do android emulation, but yak)
