David, you are in the US so you could go with a Saunders, which I considered myself (either the Heavy-Duty or the V-track) but as they are not available outside the US I found a LPL Universal 14x17" which has great built quality and can handle both metric and empire sizes (cm and inches), as they are different (30x40cm is larger than 11x14" even though they are "treated" as equivalents).
