Best Skirted Toto Toilet

Here are the parameters I'm working with:

1. I don't want to clean the base of the toilet.
2. I like the CEFIONTECT stuff.
3. We need power.
4. I'm installing 4, so I can't spend all the $$ in the world.

I would love some advice!

Thanks!!!

I have one Vespin (2-piece, therefore less expensive) and one Carlyle. Both work great, at least for me.

I'm pretty sure that the Vespin is the least expensive skirted Toto, though I could be wrong. I have one and would heartily recommend it to anyone.
