I've got one of the HPS10 Vellemann scopes and for the money you wont beat it. True it has a limited bandwidth (dont even bother going above 1Mhz) but for general workshop use and troubleshooting stuff on the car its ideal. If you do buy one get a set of rechargable batteries and a mains adapter to charge them with - it will save you a fortune in the long run.
