One thing interesting to note: the DS2000 has 192MB (DDR2) of acquisition memory. The most, as a user, that you can directly use is 113,792,000 bytes (e.g. 14k x 8128 frames) - which leaves well over 64MB which is only accessed by the acquire hardware.
I suspect that, normally, the FPGA which moves samples from the ADC is alternating captures to two different banks of 64MB acquire memory (except when in record mode). This would explain why sometimes when the DSO is stopped - and I switch the acquisition mode to Average - it averages the waveform without capturing anything new! Where would it get another waveform(s) to average the currently displayed waveform from - if not another bank of memory? However, this doesn't always work - sometimes it does - sometimes it doesn't - based on parameters that are unclear to me.

Hey Dave, I just ordered a DS2072 from TEquipment (2 days ago), there currently is a lead time of 2 weeks. They are taking all orders as pre-orders that will be charged in 2 weeks when they get stock. Make sure to mention the EEVBlog when getting a quote to get a bit of a discount!
Lucky for you, TEquipment also ships the scope for free in the US. I'm ordering mine to Canada, 80$ shipping + Duty fees :(

Looks like the only place in the US to get a good deal is Tequipment but they are out of stock. Did anyone recently place an order and how quickly did they get the scope? New to electronics.. but it seems this is a good starting scope to play around with. I have a Tek 465b but I guess I won't use that much when I get my hands on the Rigol. Seems a great group of people here!

Just ordered from TEquipment ... they were kind enough to give a discount and free shipping but the lead time is 3 - 5 weeks. Looks like it is back to using the crusty Tek 465b for now!
Marmad: I want to thank you (and Dave) for your excellent reviews that clinched the purchase. I'm sure you are responsible for a lot of purchases. Rigol should be showering with free stuff!
Cody: Thanks for that. Those shipping costs are a pain. I would have considered a nice trip to the US :)

The manufacturer discontinued the free trial option? Is this true?
