I originally had a 50 but sold it to get a 63 because I thought I'd need the extra room. I ended up not using all of it.
I was quite tempted then I read your add again and realized you weren't interested in shipping (plus I'm on the other coast)... Too bad, that thing would work well in my Ambo!
Good luck and let me know if you decide to ship.
Cheers
