14 male to 18 female converter help

I am looking for a 14 male to 18 female converter (think the opposite of a lowpro). I used to have one but a clumsy guest broke it. The last one I had was blown for me by SGW, but now that he is gearing up production of his tubes I can imagine he's mighty busy.

Anyone know where I can snag one? Last one cost me under $30, and I can't see it being worth too much more than that anyway. (This is why EDIT just won't do, aside from the overseas shipping).

Thanks in advance.

search around on scientific lab glass supply sites.

i don't have a link cause I haven't personally ordered from one, but a friend of mine got a bunch of adapters before from one.

not too helpful but it's a start.
