A Pista Concept will have the hipster tax associated with it (in my experience). You can get a previous generation FTP though for pretty cheap though if you don't mind having an outdated body style.

For $400, I think the Alien frameset is the cleanest frameset you can get with lugs.

If you are looking used, there are a ton of options of course, but with lugs it will generally be heavier because they are older frames ... this is a result of course of limited availability/options. If you can afford to be patient you will find what you want. It depends on how fast you want it.
