We looked at those and decided to go with the Coleman hot water on demand.They are a little more pricey, but we can have hot water any where. The unit has a built in pump and comes with a 5 gallon bladder with a handle (for those SAM's cooks where you have to carry water) and we also got the garden hose adapter for those comps that have running water on site and the carry case.
The unit has a motorcycle battery for power(will last all weekend easy) and uses the small propane tanks for heat.Tanks will last 2-3 comps.
This was purchased on request by my wife as she is the primary dish wahser.
