does this tool look any good?

hey guys just flicking through the internet looking into oscilloscopes and digital multimeter combos as a friend has one form snap on, id like to get one as im setting up my own business installing car alarms and will be going into audio once i leave my current job ( got to be carfull as they dont sell security but do sell audio) and id like to be more than just a fitter as i have been for a few years, id like to be able to set up sytems and such for my own customers and provide the better service then the retailers around here do i found htis and wondered if any of you guys would care to comment on it Pocket Oscilloscope thanks guys

for some reason it wont link the address is http://#.co.uk/2Msps-sampling-rate-ARM-DSO-Nano-Pocket-Oscilloscope-/280567216161?pt=BI_Oscilloscopes&hash=item41531bf821#ht_2766wt_937 ps i want to use it to view the clipping points of stereos and amps :)

Even that link is invalid.

Links to certain websites are not allowed here.  The Server filters them out.  The number of installers or install shops that have a scope is a very low number. 

Didn't notice that :) ps i want to use it to view the clipping points of stereos and amps :)

If it is the one that you can buy now for 73 dollars, I am not going to trust it.  It is made in China, and I know they can make things cheaper than any other source.  73 dollars for an oscilloscope is very cheap.

Probably as good as the Chinese car alarms. You won't need a scope for alarm work. Save up for a diagnostic tool to turn off the DTC lights you are going to leave on.

i want it for audio work, im installing alarms to start as where i work do audio so i wont be doing it as a main for my business till i leave :) and i know about the lights from experience heehee, defo worth geting

also any recomendations for a diagnostics tool that will become very usefull ? we just send them to the dealer and foot the bill as the company has plenty of cash for tht kinda thing, mind u i havent done it too many times but it still does happen and £30 - £50 a time can mount up :s
