Hi kinlin and welcome to the forum--
Sorry to hear about your frustrations.
I do not own the Sweet 35 or Composer Pro, so I cannot speak from experience with that setup, but I've been banging around her for a little while, so....
First of all, a few clarifications:
1) Lensbaby only supplies the apertures and aperture tool with their Lens Bodies (Composer, Composer Pro, Muse, or Control Freak) with the Double Glass Optic installed (that's the standard optic). Lensbaby does not ship the aperture tool and apertures with any of their optics except the Fisheye but the fisheye uses a different set of apertures from the rest of the line of optics (I'm afraid the retailer was mistaken on two counts there).
2) The Aperture Tool (with apertures) is available by itself direct from this website or you can probably find one on ebay for a decent price.
3) Any of the accessories offered by Lensbaby are for use with any of the optics other than the Sweet 35. Sorry if you misunderstood that from the website.
Don't know about any difficulties you might run into with international shipping and/or tax/trade laws where you are (i.e. I don't know if you could deal directly through the LB website), but I can tell you that Lensbaby's customer service is second to none. If you contact
kirsten@lensbaby.com , I'm sure that she will do everything she can to help you.
I sincerely hope this helps, don't get discouraged and keep shooting,
Johnny Crabcakes
