For those looking for a decent hobbyist-level oscilloscope

For all you people looking for a decent low-end oscilloscope to test and experiment with, may I suggest:
http://www.tequipment.net/pdf/OWON/EDU5022_manual.pdf· (for the manual)
Order it here:·· http://www.tequipment.net/OWONEDU5022.html
This offer just showed up (3/27/07) in my email, and has no deadline that I see.
This is a 25MHz bandwidth,100 MS/S dual-channel color-LCD unit with PC communications. It has several nice features, many of which mirror features and functions on my TEK TDS2024B, a VERY nice 4-channel 'scope.
Three big differences (to my mind):
- PRICE $368 (with inexpensive shipping!) vs $2200 to $2400, and
- BATTERY capability, optional battery pack included, NOT available on the TEK (well, OK, it can be had for another $1000 on the TPS version).
- Deeper storage (6k points) then my TEK 'scope (2500 points)!
I checked the manual on this. The specs look pretty decent. Check it out yourself. It suffers slightly from Chin-lish, but is a good translation. One thing: there is nothing I found about installing, charging, or the specs for service life of, the battery. You might want to check into this further. Maybe call these guys and see what they say.
Also, they are not terribly informative about serial communications. They claim USB and serial capability, and the picture in their ad suggests both ports are there, but the display-download section in the manual only mentions a serial connection.
It seems like a Godsend, but I'd like a few more heavy hitters here to check this out and give their opinion before the less experienced shell out big bucks for this.
Later!

Does it work correctly·in USA?

You can get a pretty good (if not better) scope for the same money or less if you shop careful on Ebay. I bought a Tek 2247A last year for under $300 - very nice, but also big, loud (fan) and heavy. There is definitely a market out there for a decent LCD scope.
