I do all of my SMD builds by hand. I don’t want an oven (frequently referred to as “firestarters”) in my apartment/home office.
PCB means no parts. Assuming that you are tackling NLC builds, nearly everything (including pots, jacks, and knobs) can be found cheaply at Tayda: https://www.taydaelectronics.com/
Buy SMD tweezers. Get a flux pen for later builds with SMD ICs. If you don’t have some from existing projects, you’ll want desoldering wick.
For your first build, do a Bong0, then a BOOLs. The Bong0 is probably $1 worth of parts, tops. It took me around an hour to build and calibrate one. BOOLs is also cheap, but there is more to solder. The best thing about those two builds is that they do not have SMD ICs or transistors, which are far-and-away the toughest parts. Both can be sourced entirely from Tayda. Brain Custard is a good next step, as it introduces SMD ICs that can still be bought from Tayda. The 1050 Mix Seq is intimidating, but it’s probably the next step after that. It introduces SMD ICs which you’ll need to source from Mouser. Most of the newest NLCs builds fall in the 1050 range: order 98% from Tayda, buy a small handful of parts from Mouser.
As a beginner, avoid Feague, FlipFlop Chaos, the new Sloths, and the Phaser. They can still be built with Tayda and Mouser parts, but you’ll need to track down a lot more parts beyond ICs. Sloths and FFChaos have a bunch of weird resistor values, the Phaser has transistor matching, and for Feague you’ll need to chase down a tempco resistor along with some other expensive parts.
@Jonny, I hate saying it, but the Microbraids is a beast to build. The ICs are tiny, and the resistors/capacitors are 0603. Start with an 0805 project if possible. Also, for 0603 builds, you’ll want to buy a smaller tip for your iron. O+C is much easier than Microbraids, but the DAC is a real pain. That DAC is a good introduction to Microbraids, which has a large number of ICs like that (and worse!).
