Thanks to Singularity for starting this poll! We've contacted the vendor on your behalf and they've made the Macally Bamboo Laptop Cooling Stand available.
I've had an mStand for a few years. Only problem I've had is the rubber bumpers on the front lip came off. Replaced them with some Sugru. As far as weight goes... I just put Vol 1 of the Complete Far Side (~8.5 lbs) on it, and it hardly moved. It did flex with the entire box set, but I doubt you have a 17 lb laptop.
Can anyone vouch to the quality of the mStands? I'd like to vote for a design that's open ended much like that one (my current one looks more akin to the Elago L3 and tends to collect alot of dust under the stand). I have an Asus G750 laptop, which weighs quite a bit, can anyone guarantee that it wouldn't give way after a short period of time?
I have watched quite a few reviews on them. From what I can tell, these things are rock solid. They are constructed out of a nice, heavy piece of aluminium. These things won't be giving out on you in this lifetime.
