Obviously, the ATTEN one would work fine, but the DSO150 doesn't have the bandwidth in reality. You want a bare minimum of 10x the sampling rate of the signal you're measuring, and the sampling rate of the DSO150 is 1Mhz, a 2x sampling rate.
The ATTEN is very similar to the one I use, AAMOF, I suspect it's the same one with slightly different panel markings. All the controls look identical as well as the bandwidth and sample rate.
