Hi,
I have more of a software background, but I have been playing with RPIs and Arduinos through different small home automation electronic projects. I have been reading through the Art of Electronics for a few months and I have a lot of new project ideas, but the lack of a scope and a good PSU is becoming a limiting factor. To sum it up, I think I am now ready to start acquiring more equipment to push further. I would really appreciate to get the Tequipment member discount. Thanks!

In regard to a PSU, I'd suggest including quality used linear supplies to your consideration as you can get them for pennies on the dollar of what they went for new. Meaning they can come in cheaper than the inexpensive units currently available IME.
Generally speaking, your funds will go further by purchasing multiple output supplies (dual or triple channel vs. single channel models).
With the recent closure of ITT, their former T&M gear is still turning up on eBay at very decent prices. Take a
GW Instek GPC-3020 for example; triple output supply shipped for under $100 with both CV & CC operation (2x channels @ 30V & 2A, and a fixed 5V & 3A). There's other brands as well, including top tier names such as HP/Agilent, Lambda, and Systron-Donner (not all inclusive; latter brands *can* offer better deals IME as they're not quite as well known/popular).
