The MB200 is 7.5" wide and a vertical One10 is 11.5" wide, so 2" space either side. There are loads amps that would 'fit', including anything from the G-K MB range (200, 500, 800 + 500 and 800 Fusions), both Aguilar Tone Hammers, Mesa D800, Peavey MiniMax, any of the MarkBass Little Mark series (and others)... Demeter Bass 400, Minnie 800D... and on and on.
If you place the One10 horizontally (say, on a stand) you get another 3.5" and this opens the possible range of amps you could use without overhang quite considerably. Ampeg PF500, FP800, Ashdown MAG 420, RM800... Demeter VTBP-M-800D! And so on.
