Hi Jason,
I have one of these machines which is called a Tcm 403 bought from Techniclean about 8 years ago, and have not seen one for ages!
I must agree they are an excellent machine and although I have an extracta excell, i much prefer the old one even though it's a bit basic.
One good thing about them is that they are pretty light, esp compared to the extracta!
Wanted to buy another recently but cannot find anyone who sells them.Techniclean said they were waiting on a new model but do not seem to be very forthcoming.....!
All i can say is that they are easy to use and use same parts as any other machine.
Cheers
steve
