I understand all toilets are the water saver type now, some do a good job of flushing, some don't. Any advice on make and model appreciated.

Check out Consumers Reports at your local library - they test a bunch
of models. Last test was August of 2005. I was looking myself
recently, and standouts were the Elger Titan ($350), Gerber Ultra Flush
21-312 ($275), and Eljer Aqua-Saver 091-7025 (CR Best Buy, $200).
Don't know about the price mentioned above - cheapest list price in
their test was $160. Hope this helps.
Good luck,
Andy
