Don't expect dishwasher reviews and such, but there are some items for the home which we've found useful. 

Years ago our traditional hot water heater went out. With multiple teenage kids we needed more capacity anyway. Since we are propane, it was going to be a special order anyway, so I started investigating tankless heaters and ended up installing one.

It's largely been a very good thing, but we learned some things along the way that may be useful to other tankless owners or those considering them.
