This is only specifically made automotive oscilloscopes I would recommend for the beginner, or anybody who is unsure of the settings on a non-automotive scope, its a good simple tool, with a fair sized LCD screen for about 550ish (28-04-07) downside is it only has an analogue bandwidth of 500khz.  It has a pre-programmed memory and it is a third of the price of "big named scopes" from Snap-on (Sun), Sykes Pickavant, Mac, OTC, Bosch FSA450, Vetronix, Crypton or the discontinued Fluke 98-2 or Bosch PMS100.  But if you don't mind studying the subject of scopes and learning how to set one up.  You can find allot more scope for your money if you have 500 to spend.
