totally in love with the cadco OV-250, but I believe it has been discontinued with a model which has 0.5” more space between racks. the OV-250 has only 2” so for 2” high pans won’t fit.
this oven is so even, so great, for sponge cakes I don’t do anything differently, but perhaps the cake tops domes slightly forward because of the fan, almost unnoticeable. for butter cakes, I do lower -25oF
it fits 9” pans perfectly, 1.5” high, and 3 at the same time (oven has 3 racks). YES the little spacing of 0.5” left on my OV-250 is enough for this oven which bakes so even. also, if your pan touches the oven walls, roof, or floor, or is very near, it is still even, as on a traditional oven would need an otherwise 3” or so clearance.
i believe this oven won’t fit a 12” pan, so that is my con, but who bakes 12” pans anymore? adapt, adapt.
it heats up in 7 minutes, believe me, and it recovers in a few seconds!
this is the most used oven at coffee shops, it is built to last and can be left turned on all day long.
at the end of this comic video, you can see my OV-250

note that there is a larger brother, which you can fit half sheet pans, but it is still 2” or 2.5” shelf clearance
it retails for around $500, but really is the best countertop toaster oven like you will need.
