Alternatives to the Sun CR18 rim.

I'd like to update to a new 700c rim on a 1978 Trek road bike. I want a rim that keeps the old-school look of the bike, and need to avoid any rim with a modern aero appearance. It would be great if the rim is 21 to 23mm wide. The hole count needs to be 32 and the color or finish should be silver or satin.

The Sun CR18 rim fits the description. Any other modern rim I should consider?

Some good recommendations above, but the CR18 is, well, there ain't much wrong with them for the price.

That doesn't square with my experience. I've found the DM18, at least in the 26" size to be extremely robust. I don't have any of my own bikes running on them in the 700c size, but I sold plenty of bikes with them to hefty riders with no issues.
I'm riding one pair of wheels I built at least 6 years ago with 26" DM18s and I've never had to touch them with a spoke wrench.
I would conclude your wheel was a faulty build.

+1 for either the Raid or the Diagonale, they are pretty faithful repros of the Rigida Red Labels. Which see, both they and the Super Champions are always available on That Place Online.

The Sun CR-18s are probably the best value, but the Grand Bois and Velo-Orange are also worth considering.

A bad build vary well may be true. I've had other Alex rims and didn't have a problem with them. Mine was a 700c.

For me the CR-18 and M13-II are the rim equivalents of the Panaracer Pasela tire: they look good on vintage bikes, they perform well, and they're not expensive. My only beef with the CR-18 is that it doesn't come in 650B.

There was an initial run of CR-18 rims in 650b. I bought a pair, my first foray into that wheel size with my Kogswell P/R frameset. Well, Sun screwed up; those rims were slightly oversized, making it almost impossible to mount or remove tires (I did it with the Panaracer Col de la Vie tires that were about the best you could get at the time). I donít believe Sun ever tried again.

Velocity A23 or Velocity Quill are two modern-ish rims that both come in either silver or polished and neither one would look out of place on a vintage ride.

The A23ís have a beveled V shape that is somewhat comparable to the chamfer on the Sun CR-18 which is a nifty little technical detail. The Quill rim has more of a half round extrusion which is nice looking as well but in a slightly different way.

The internal rim width on these is 18mm on the A23 and 20 (or 21)mm on the Quill. This allows for great sidewall support for 25 & 28mm tires. Also both of these rims are tubeless ready, which may or may not matter to you. But having this option for a classic bike should not be underestimated. Todayís road tubeless tires are excellent.

Yes, since then I've put Velocity A23 on a De Rosa and H Plus Son TB 14 rims on a Eddy Merckx and a Pinarello.
