Juno seem pretty good. Normally they’ll shave a little off the price and they’re very flexible about returns. My AK needs to go back at some point cos the screen has issues, they’ve said I can keep it as long as I need to finish current projects first.
Gak have always been good in the past too.
I’d maybe avoid Guitar Guitar. Had a few years of no problems with them but my Op1 purchase was a joke. Took them so long to get me a functioning unit after mine arrived faulty. Had to chase them up a LOT before they even confirmed there was a problem and it even got sent back to TE. Could have just been a bad employee/one off I guess tho. No issues with them before that.
