I managed to find an Avenger reseller who had posted an only-slightly-out-of-date catalog PDF on their website. The A0045CS is part of a line of clone products in varying sizes. There's a 0030, 0035, 0040, and 0045. The last two digits are the max height when multiplied by 10cm (so the 0030 is 30*10=300cm tall). If there's a B after the number, it's a black aluminum stand and if there's a CS after the number it's a chrome steel stand. So the A0030CS goes to 118" (barely shy of ten feet) and weighs 13.2lbs, a savings of 4.4lbs. That's not quite as much weight savings as I hoped. However, the A0030B only weighs 7.7lbs, which is a savings of 10lbs, and yet has the same specs as the steel version.
I have to admit I'm a little nervous about getting an aluminum stand. I moved from midrange aluminum stands to high end steel stands, so in my mind the dramatic increase in quality, reliability, durability, and sturdyness that came along with moving up to a higher class of stand is also tied up with the materials choice. I'm just nervous that if I go back to an aluminum stand, even a high end one, I'll end up being pissed off at it because it's frustrating to use just like the mid-range aluminum stands were. I also am not sure how much of the stability on a hillside I'm loving in the A0045CS comes from the weight of the steel stand vs the large footprint and leveling leg.
