Apparently they sell the ADS1102CA, and after looking at official website  
http://www.attenelectronics.com/products/rf_microwave/ADS1000.htm
I see that:
ADS1102CA:
Bandwith: 100MHz
Sampling Rate: 1GSa/s
Equivalent Sampling Rate: 50GSa/s
Memory Depth: - Single Channel 2M
                     - Double Channels 1M/CH
Rise Time: <3.5ns
Input Impedance: 1M?||13pF
Sec/div Range: 2.5ns/div-50s/div
Roll?100ms-50s/div

Seems to be good ? What do you think?

From this data it seems a good alternative to the Rigol, and it's cheaper. Unfortunately, while the Rigol has been tested and reviewed by many users, the Atten has not, so there could be minor details which make one of the two better than the other (about usability, for example).
However, consider that for many people these Atten products are copies of Rigol ones, and ADS1000 seems a copy of DS1000CA, the old Rigol series (take a look at this forum, too: http://www.rcgroups.com/forums/showthread.php?t=663958&page=33).

Thanks for this great information!
I have checked the 2 DSO (ADS1102CA and DS1102CA: they're the same...)
Atten seems to be a copy of old Rigol as you said...
So I will buy a Rigol DSO !

One question regarding the Trigger "Sweep".  There is a setting "Single", which per the documentation captures a single waveform.

My question is, what comprises a "single waveform?"  Is it basically until the trigger condition goes away, or something else entirely?

I'm on the same way, too.
It's been a few months now that I had this intention, but still I haven't bought it. For a time I wavered between DS1052E and GDS-1062A from Instek (which is a more reputated mark), but price has a big influence, since this will be for my hobby only (although..who knows?), and it seems that quality is good also for the Rigol (besides there is the 100MHz hack). Now you can find it on DealExtreme at 362$, and the €/$ exchange is favorable for us in Europe now, so I'm going to buy the Rigol these days.

Single mode allows the scope for a single trigger to be activated. So it could be called "one-shot", in other words it waits for the trigger and then acquires data until it reached the end of the screen or the end of the memory. Now I haven't one by hand, but I think it should acquire one screenshot, since by setting the sampling rate (or the timebase, if the ratio between these two is automatically set by the scope) you can decide how much time you'd like to record.
It is used for seeing rare events, or events that are each different one from the others, even if they all could activate the trigger For example, if you want to see the response of a program on an MCU to the first time it receives a byte on the UART, you can set trigger mode on "single", falling edge trigger on the RX signal and a proper timebase, so that the screen contains the whole response of your interest. If on the UART there will be other data after the first byte, and if you were on "auto" or "normal" mode (instead of "single" you will see the series of the various responses together, so not letting you see how the first was.
