The Rigol DS1052E
Simon:
I was also considering an exrernal power supply but for all the wires coming of the psu, its as though some parts are on the main board

they are very similar, but there's differences in the pcb for sure. The 1052 looks like it's using a Cosmo KAQY214S SSR ( http://www.cosmo-ic.com/object/products/KAQY214S.pdf) instead of the mechanical relay of the 1102. Could this limit the bandwidth?
other than the components ralated to the SSR everything else seems the same to me?

The board in my DS1052E is exactly like FLolic's-- down to the FT relays and silk-screened labels. The only difference is the minor 'patch' on the LCD driver IC on mine. I believe Dave has a slightly earlier rev board.
I would suspect the 'shaved' IC's in the analog section-- there's has to be a reason why they insist on defacing the labels.

my 1052 arrived today, purchased through goodlucksell on ebay, was decent of them to declare it's value as $30 for customs ;D
really quite impressed with it so far
Simon:
I really wonder how this customs business works, if I can put 10% of the real value down what is customs achieving, don't they ever check stuff against its declared value. most small stuff I ever bought from china on ebay comes as a "gift"
flolic:
Here in Croatia, I had to pay 23% VAT on real value, not declared (declared value was 60$) >:(
It's all up to a good will of a custom officers, if they think that real value is greater than declared (and in this case it obviously is), they ask for a Paypal invoice. If you don't give them invoice (or altered it to smaller amount ;D) they can, and will, easily check ebay auction. Then you are i trouble ;D
OTOH, smaller packages, not necessary low valued, usually pass without any duty...
