I wouldn't spend my money in China! It seems that all these boards do is provide holes for sockets. IMHO, one would be better off by building on a metal sheet and using point to point wiring or fiberglass modules with Y studs like Keystone sells. Ray
Yes, that's been my approach in the past, broadly speaking. What are Y studs ?
Keystone Electronic Hardware makes Military fiberglass boards with Y solder posts. You can buy them in any config with any type of posts (double sided, single sided, Y ). Keystone Electronics Corp. - Keystone Electronics World class manufacturer of interconnect components & hardware catalog page 131, (MS27249). These are not as cheap as the china product but Mil spec quality. There is another guy on ebay that sells a similar product. Many of the tube type classic preamps used this type of construction; Harmon Kardon, Marantz, McIntosh. You could also make your own if you have a drill press. I found the posts on ebay. Concord electronic Hardware also makes them.Concord Electronics, Inc. Store | About Concord Electronics, Inc.

Try building them with soda straws and you will see Y studs.
Hello !
I'm using these parts for some years...
Most of pins are "metalized thru holes", not like usual PCB, so you can solder-unsolder many times
The boards are rigid, due to it's thickness ...

I realize this is an old post, but the OP is still an active member, so I thought I'd chime in. I have one of these boards (and they're available off of AliExpress for as little as $12).
I have used mine for a breadboard. Here's a pic with a custom amp breadboarded. LOVE it! I've got an amp on it right now and yesterday decided to test out a design for an external tube preamp/overdrive pedal, so just added the tube and components and ran it straight into the input of the amp that was already breadboarded. Love the flexibility it gives me and it's surprisingly quiet considering the lack of a chassis or any real shielding (other than some shielded coax).`
