I got this unit which offers you great capabilities for a very fair price. Probes are included as is the software. At http://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso this unit is widely discussed and even an improved version of the software is available for download (called "Open6022BE"). Also hardware mod's are suggested there. All in all a usefull piece of equipment and good value for money.

First of all, I think it's an excellent value at $80. I would get one again. That said, I'll now list the weaknesses. The triggering is poor. It's hard to get a waveform positioned exactly right on the screen. There is no AC coupling. DC only. The scope is NOT isolated from USB ground, which on a computer is typically connected to the ground on the wall plug. You cannot connect the ground clip of a probe to (say) line voltage to take a reading. You'll need to either use an isolation transformer, or a laptop running on batteries (not plugged in) to do this sort of thing without blowing something up. There is no mention in the specs, but it seems that actual input voltage to the scope is limited to 5 volts. This is not surprising, since the USB voltage is 5 volts. So if you use the included 10:1 probe to measure something that is (say) 75 volts, it will read as 50 volts. If you want to measure between 50 to 500 volts, you need a 100:1 probe, not included. There trace buffer is deep, but the only way to scroll is to drag one screen at a time. This is a software issue, possibly they will add a scroll bar in some future version. There is no equivalent of a "delayed sweep" like on HP scopes, that can magnify a particular portion of a trace. You can stop a trace and magnify the data, but may have to drag through hundreds to screens to get to the part you want. The software only works on Windows XP and later. It does not load on Windows 2000. If you have Windows 7 or later, you need to go to the Hantek site to get drivers that are not on the included CD. There is OpenHantek software that runs on linux, but it does not support the 6022BE at this time (2013). Do not expect any support from the manufacturer. Their site is very sparse with English help. And some positive surprises: The two included probes are switchable between 1:1 and 10:1, and decent. I thought the 20 MHz was marketing hype, and was prepared for a 2 MHz scope, but was actually able to observe ringing at about 20 MHz. It's surprisingly easy to export the screen as either a bitmap file, or comma separated value data file
