Have you considered graduating to an A2000? I know that I'm not the first to suggest it. As much as I know you must love that A1000, I'm positive that there's another model close enough to it that you'd love just as much - if not more. And with the trouble you seem to be having with finding this glove, you might not have a choice but to switch.
With the used market (or even trade market here on the forum) being what it is, you can definitely afford to experiment with a few models, dumping the ones that don't cut it, and find the one that's right for you. Most of the people here are fans of the higher end offerings - that's probably the reason nobody here has an A1000, let alone that specific model you're looking for. The other thing to consider too, is (as you've probably found out for yourself) A2000s are WAY more plentiful.
Whatever you decide to do, good luck!
