What does it cost to install a macerating toilet?

We would like to add a small WC in the cellar where there is no gravity drainage, so a macerating unit seems the only option. What should we expect to pay for a Saniflo type toilet supplied and fitted and are they reliable enough for daily use?

"The cost of supplying and installing a Saniflo macerator toilet in the UK always ranges between £800 and £1,500 in total, depending on the model and the complexity of the electrical and plumbing connections. Saniflo systems are completely reliable in everyday use, as long as strict operating and maintenance rules are followed"
