I'm in a similar situation. I've been looking at the Atten and right now my price point right now is just above the Atten 25Mhz DSO ($300US).
Looks like the asymptote for the Rigol 50 MHZ right now on ebay is $384 to $386US . The best price for a top rated seller for the DS1052E is $391US being offered by 'testinstru'.
Every time I go on ebay knowing I have the funds to buy an Atten, I pull back, pop in EEVblog #37 and my hand closes the ebay door!
I will ride the impulse out and Dave will lead me to the promised land!
I will show the Rigol safely tucked away in its lair when that day comes!
p.s., There is a bitscope bs-50 out on ebay being sold by a pawn shop in Florida for $279 or best offer. I've had to slap my hands to keep off of that as well. That deal sounds like a crap shoot to me.
