i bought one for about the same price on ebay too.. be careful that it is in fact "new".
When I got mine, it was not new after they said it was (even after i called them to complain), and needed to be hydrostatic tested.. was a pain in the arse.
edit**** why the crap don't they accept paypal.. strange...
Looks like a good deal but make sure the only date stamp is the one they say, otherwise it is not nearly new. Also, I can't tell, but are the threads on the outside for the hookup? (need female fitting to attach too)
