Hi.
I'm actually in the exact same situation as you are in. I have been debating with myself for the better part of 6 months on which path to take in regards to buying a scope.
As much as I would like the Agilent, mostly because of the very good support you get, and that I try to buy non-Chinese if at all possible, though that’s seems to be increasingly impossible for each year that passes. I have pretty much reached the same conclusion as you. Rigol is the way better bang for the buck product, and taking in to consideration that this is for privat/hobby use and don’t expect to make money of whatever I conjure up, then it’s a bit of a no brainer.
By choosing a Rigol 4024, I get 200Mhz and 4 channels for the same price I would have to pay for a 100Mhz 2 channel Agilent, even counting in the 15% student discount I get since I work as an electronics engineer at our Technical University here in Denmark. One of the things that was swaying towards the Agilent was the upgrades, but Agilents is insanely expensive, almost a 1000euros just to get the 16MSO unlocked, then add 750euros for the UART and 750euro for the I2C and SPI that I’m interested in just makes the Agilent way to expensive for me to justify for hobbyist use. The arb gen is nice, but I consider 1 channel arb gen more a nice “toy” or student lab tool then actually being a really useful tool.
So I’ll probably also go for the Rigol 4024, buy a dedicated Arb generator and good USB logic analyzer, I have been eyeballing the logic analyzer fra Acute, they are not cheap, but on paper they look like they are kicking arse and taking names.
Would love to hear more from you about your impressions and thoughts on this scope, and from others naturally before I pull the trigger on buy this scope, and with a bit of luck our favorite crazy aussie bloke might get the chance to have a wee look on it too soonish.
