Just fyi for fellow EEVers
TE has a 30% off deal on Rigol for the 4th of July (day only?). It doesn't apply to the DS1054Z but it applies to other models, so a DS1074Z is $328.30 after the discount. It also applies to accessories including licenses; so for example if you are a DS or MSO 2000 series user and you wanted to buy a BND-MSO/DS2000A bundle license (includes AT-DS2 Advanced Triggering, CAN-DS2000A CAN Triggering Decoding, MEM-DS2 Memory Upgrade to 56 Mpts, and SD-DS2 RS-232, I2C, and SPI Decoders) it's $179.90 for the bundle license.
If you call them they will give you the checkout discount code.
The DS1074Z at $328.30 with free shipping in the U.S. looks like a very good deal.

Happy 4th of July
