Lime in well water - need new toilet

What style of toilet is best for lime-laden water? The lime scale has ruined our current toilet (you can clean the scale in the bowl, but it's clogged the holes in the rim and cannot be removed).

I was thinking of going with the Toto Drake, but am not sure it will stand up to the lime problem. Help?

TOTO Drake II CST454CEFG

Get the TOTO Drake II, CST454CEFG with CEFIONTECT.
It has two large outlets at the top of the bowl for the rinse
Perfect for water with lime.
These things are flying off the shelf right now.

Excellent! That's what I was aiming for and have found a (kind of) local dealer to get one from.
