Bicycle Mechanics - Front loading stem for threaded headset?

I'm trying to put bullhorn bars on my fixed gear bike, but they bend too sharply to fit through the quill stem. So I'm looking for a front loading road stem for a 1" threaded fork. Does anybody have one to recommend? Or should I go with one of those threadless adapters?

I found this thing at Nashbar, http://www.nashbar.com/profile.cfm?sku=12673&SRCCODE=1067, but I can't tell what the attachment mechanism for the front plate is, and I'm wondering if it's one of the flimsy fold-open ones.

Profile use to make a decent open face 1" quill for not alot of $$.

I recently put this stem on my S&S coupled bike for ease of packing. it is a fold open style stem, but not at all flimsy. I haven't ridden it much yet, but it has been great thus far.

Unless you need to take your bars off frequently, I think you'd be better off checking the forums for advice on fitting bars into stems. there are more than a few threads on the topic.

Profile makes some pretty nice threaded stems w/ a removable face plate. I have a CODA on my bike, but its a rebadged Profile.
