Well, The test in New York by Varsity Plumbing, had several toilets that did very well. At the top of the list from what I have heard were the Western Aris and the Gerber Aqua-Saver.
The first toilet sent to Dave Barry, was the Western toilet. When that one broke in shipment, the Gerber toilet was used. Both toilets are very good toilets.

The safest way to ship toilets would be on a pallet. Unfortunately, you would be looking at a minimum order of four toilets.
