[sdiy] DSO recommendation please

I've been looking at this Rigol DS1052E scope with great interest. It 
seems that somebody out there has found a hack to re-program it to get 
100mhz response. At $600 USD, it looks to be a pretty good deal. Here is 
a link to the hack:

I'd be curious to hear from anybody that has used this scope. Would this 
fit your bill Tom?
