+1, just purchased mine from Amazon UK as I've been dithering on it this past week and they are now down to just 1 item left in stock.
620GBP with sales tax, so ~646USD or 593EUR without. Not as good as Veteran68 (kudos, great deal, see you in the hacking thread at the weekend

) but not awful and likely better than purchasing direct from Rigol EU tomorrow as I'd get hit with additional shipping charges and possibly customs duty collection fees too being outside the EU.
Didn't need it but could no longer resist at this pricing. My original intention was to go with the MSO5k and supplement with a DHO800 when they became available. Will probably have a good play with it over the Christmas holiday season, which will decide whether it has a place on my bench full time or gets put on that well known auction site. I'm very happy with the 5k, BTW.
I messaged Rigol on Amazon prior to purchase and: "Hello, our stock in the UK are all the latest machines, you will receive the machine with DHO logo, HDO is the old logo for this series. Thanks"
The Amazon deal includes an official memory upgrade license, so just the bandwidth to "enhance".
