I have arthritis too. I have an older HQ - the HQ16. If I could do it again I'd definitely get the HQ Avante. I have 2 local dealers [I do prefer one over the other though.
I upgraded my HQ16 a while ago and a friend had no trouble setting it up for me. I just 'borrow' friends and barter as much as I can.
HQ support via phone is awesome and easily available.
