I use a ton of SMD protoboards. Just cheap ones off ebay. They are great for testing out chips before you order your boards.
Only problem is, is there is a huge variety. The ones I tend to use most are QFNs and SOIC . I also tend to use a bunch of 0.5mm pitch generic ones.

You can just order a grab-bag of a dozen different types.

I haven't used through-hole in a project for a few years now and don't miss it a bit!

The components are cheap enough IMO.

Any thoughts on SMD protoboards to practice SMD soldering?

The way I pick Ali stuff is sort on Orders and then pick a top seller

I don't see any on ebay unless you're technically referring to the adapters that translate SMD to DIP?
Dubbie:
Yeah just the adapters. I tend to cobble together a bunch of passives on the same board. Often they are double sided with a different footprint on the other side, so you can solder on some passives there if necessary.

You’re in the US. You can have common parts on your doorstep the next day from any number of legit distributors. Yes, it will cost more than getting them from Shenzhen, but you don’t have to wait 1-4 weeks for them to arrive. If you can wait 3 days, shipping is quite cheap. For a typical “weekender” hobbyist, you can have parts every weekend if you remember to order them on Sunday/Monday.

It’s more important to get started than to start at maximum theoretical economic efficiency.
