Help finding new 4 arm perc downstem

I purchased a new ash catcher while on vacation in Canada and after getting back to the states I tested it out and loved it. It's a beaker style ash catcher with a 4 arm diffusion down stem. I was cleaning it out after first use and while rinsing it and cleaning it I broke off 2 of the 4 arms
Here are some photos of the downstem and beaker opening:

I believe grasscity sells the exact replacement: http://www.grasscity.com/us_en/review/product/list/id/8153/ is that correct? I did some google searching on ordering from grasscity and it really looks hit or miss, some people get their stuff in a timely fashion, some people have to wait months and some people never get it all.



edit: the other 2 diffuser stems cleanly broke off and are still intact, is it possible for a glass blower to just re-attach them?

Ill be driving down to SeaTac this saturday and tried calling a few of the shops in the area, some shops think they have 6 arm in 29mm but told me to bring my piece in (only used once and then I cleaned the hell out of it).

Does anyone know where I can get this in the greater Seattle area (or even between Olympia and the Canadian border along I-5) or any online stores that will ship within the USA?

Thanks!


Also the other 2 diffuser stems cleanly broke off and are still intact, is it possible for a glass blower to just re-attach them?
