Stowa, IWC and Laco (although IWC is definitely over 1k). Stowas are a bit small in comparison to the 55mm originals though so I don't get really hung up on whether they are an original maker or an homage.
I have a few Stowa straps. I would avoid the $20 euro ones. They seem alright at first but they don't age well. The other one I have is the black nappa leather. Very nice leather and holds up well. I imagine the croc is the same.
The last AD I went to told me that previous models were pretty much obsolete next to the new ones. They are strictly trying to make a buck. That is bad advice though.
Edit: Actually not an official AD so that might be the difference.
Picking ones not mentioned (because a lot of good ones are). Make sure not to count VAT:
I kind of dig the new Tutimas even though they are getting mixed reviews. I believe their new pilot can be had for less than 1k.
Stowa does have great pilots but what about Laco? They also have some history and they have nice 45mm brushed steel...
