Dont get a CFR spotting machine. Although powerful the hose is a nightmare as its a flexy consantina (if thats how you spell it). All lovely when just sitting there but the second you turn it on the hose wants to pull backwards to the machine all the time. So everytime you lift the handtool it physically pulls your hand back which is extremely annoying!
Cost me 300 or 400 quid and Ive used it about 6 times.
