Did I say I was the one who got stuff seized? I'm saying, read again, that Customs has seized weirder things in the past for no other reason that it was a bad day.
All kinds of parts, add-ons, etc have been seized before. Even the small spring sets that go into mechboxes, just because the container said M-16 or something on it.
I'm saying that dealing with Customs is a gamble at all times and you depend on their whim when you order anything. For many things, the gamble works, sometimes it does not.
If the gamble is worth it to you, heck, go for it.
I buy all my stuff from our retailers or local hobby shops. I also beleive in supporting Canadian Retailers; if we dont, one day we'll really bitch that we cant get anything into the country.
