A few thoughts...

I'm glad my mention of Terraferma might help! I don't know Terraferma's work, but I do know two people on the forum who have his bikes and are fans...I can put you in touch if you'd like. I think his prices are attractive, but his aesthetics aren't my thing (that's obviously subjective).

The only 650b bike I've ever had is my triplet...those wheels run quite well. Not much input, sorry.

Powder coating could be a GREAT option - and some powder coaters do a fantastic job. We have one near me called Bonehead Performance...they're a little pricier than most, but their work was terrific. My wife is tough on bikes and her powdercoat has held up very well. I'll post a photo and could do some close ups later if you're interested. I'd gladly facilitate or help out and I've had folks who see my wife's bike say it's the best powder coating they've seen. Bonehead does a LOT of bikes, and I think that helps.

There's a painter in PA called Fresh Frames...they did the paint on my Bilenky. It's probably the nicest paint job I've seen (and that includes Joe Bell, Ed Litton, Southwest) and it's thick and pretty durable with a TON of clear on it. It's help up to sign leaning and abuse pretty well, though not as well as a powder coat will. They won't deal with you, but they might deal with Mike if you're interested (I'll post a photo).

Steel is definitely the least expensive if you buy new - and it holds its value better as well. If this isn't a "price is no object" build, powder coat would be a very smart option IMO.

I'd talk to Dave Kirk about a sports tourer build...his work is, IMO, exceptional. He'll probably be considerably more pricey, but he's also a more established builder.

If you want a really cool, unique touch...consider a custom headbadge by Jen Green. Her stuff is very high quality, reasonable and FUN.

I know you know this, but don't forget the most important thing on the wheel are the tires - regardless of size.
