Those guys seem to do a similar range of stuff to www.dealextreme.com with = the addition of the test equipment items.=20 Always worth trying them for something oddball that you just have to play w= ith before buying anything big I'd say.

Or grab a second hand version that has the original firmware.

Have tried to convey the pressing need for a nice new shiny Tek/Agilent/HP to my business partners... :-) It's a chicken and egg thing - to design a high speed scope you need a *higher* speed scope :-) Anyway - here is a look at the insides of the Rigol: http://www.eevblog.com/2009/10/12/eevblog-37-rigol-ds1052e-oscilloscope-tea= rdown/ Hope some of that may help a little (apologies if it just confuses things..= ) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
