I think you're talking about the Vellemann "pocket" oscilloscopes (you have to wear the special trousers! :-)

I'm pretty sure you do get a probe with the 10MHz version, and it doesn't have an RS232 interface, so there's not much point in supplying a cable (or 
was that what you meant - the lack of the interface?)  You get a soft case I believe.  As a matter of interest, do you know what the 40MHz version's 
RS232 interface does?  Maplin's information barely mentions it, so I wonder how much use it is.
