Where can I find a 280cc Theoben Tank?

[SpiralGroove]

Hey guys,
I was considering buying a 280cc Theoben tank for my BSA R10.  I saw where another member got 100 shots at about 920 fps in .177 caliber (Huma regulator installed too).  Has anyone purchased a (NEW) 280cc bottle from anyone OTHER than RAW ($168) ?
I won't pay close to $200 for this upgrade .  There must be other sources that can ship to the USA?
Not in a big hurry, but just want to get things lined up, if, and when I decide.

Any help is appreciated .

Check with Joe Brancato ... he had some advertised earlier in the season.
Then again ... Martin may have purchased them all

Thanks Scott,
I called Joe and he's out of 280cc bottles, but maybe able to get one?  We'll see.  He mentioned the difference between the UK prices ($110/$120) and RAW ($168) were likely shipping/taxes/duty .......

Sounds like the 280cc bottle is a marginally effective, upgrade ($$ wise) vs. the Huma regulator. 
I'm gonna test this gun a bunch before I do anything; however, this gun would really be something for only $1,277
Gun - $989
Huma - $120
Theoben Bottle $168
