Heres the breakdown for popular 30mm rims:
Weinmann DP18...
687 gms

Velocity Deep V...520 gms (claimed), source:
http://www.velocityusa.com (weightweenies consistenly reports 50-60 grams more than claimed)
Kinlin XR-300 (aka IRD Cadence Aero)...455 (claimed), source

Given the tendency for companies to underestimate weight, I suspect the Weinmanns probably weigh more than claimed. I would not be surprised if they were 700+ gms. Deep V claimed weights also appear to be off. Kinlins on the other hand weigh just about the same as claimed according to weight weenies. This is consistent with my own experience with Kinlins. I've measured 4 Kinlin xr-300s and they were all within 10gms claimed weight.
Comparing the lightest to the heaviest 30 mm rim, Weinmanns are 200-250 gms heavier per rim. That is about 1 pound per wheelset. Choosing Kinlin XR-300s is a no-brainer, especially considering they are not very expensive.
Its worth noting that Kinlin makes a 38mm deep rim that is 550 gms...8mm taller and still lighter than actual Deep V weights and lighter than Weinmann DP18s by 100+gms. This rim however is pretty expensive...

I have those 3 rims sitting around.
XR-300 is always UNDER 455g
deep-V is around 580g
DP18 broke my scale.
construction quality, XR-300, hands down best.
DP18, surprisingly round and true. slight burrs here and there.
deep-V, slight burrs here and there, slight hop or dip at the joint. nothing terribly wrong, but worth noting.
Inner width and related function of tire stability while loaded laterally, deep-V is the best, followed by XR-300 and DP18.
XR-300 has 14mm inner, 20mm outer
deep-V has 15mm inner, 21mm outer
dp18 has 13mm inner, 18mm outer
Strength wise, deep-V should be the best, but at 30mm depth, all rims are fairly strong. It's worth noting that deep-V has an extra thick wall at the spoke eyelets, which require 16mm nipples, compared to the other two, which use the standard size 12mm nipple.
All things considered, XR-300 is the best deal. deep-V is not worth the price premium unless you get one in something other than black. DP18 is fine, as long as you don't intend to use tires fatter than 28mm on it, because the inner width is too narrow.
and I think we all know the HED ardennes rip off velocity A23 claim to fame is the outer width being 23mm, giving the tire a more stable platform to mount to.
PS. sun CR-18 has 22.5mm outer width and 18mm inner width, but manufacturer claims rate this rim at 28mm tires being the narrowest you should use. Not that it's stopped people from using 23mm tire on it without pinch flatting.
