I think kodiakblair is right. Finding an older, less-popular American-made instrument outside of the US is going to be tougher than finding one here (that is, in North America). However, that's not to suggest that you shouldn't try! I'd take a $400.00 US Peavey over an $800.00 Fender any day. I've got a 1981 T-40 and a 1982 T-45. Both have P-Bass width necks (about 1.65"), but a flatter profile that makes them very comfortable. The T-40 is definitely the more versatile of the two, but the T-45 is no one-trick pony. With the switchable single coil/humbucker pickup in the P-Bass "sweet spot," you can get a number of different useful (i.e. gig-worthy) tones. I've heard the T-45 sound described as a Precision Bass on steroids, and I think that's pretty close! Both are extremely well-made and (IMHO) equal in quality to any other mass-produced American bass. And yeah, some of the T-series are boat anchors, but not all of them. Mine aren't much heavier than some of the dense 1970's P-Basses I've played...
You said that you were looking at a bass that was in "excellent condition, almost unused." One thing I've found after owning a few older Peavey (and other...) basses, is that there's often a reason that 30 year-old instruments are still almost unused: they're not the kind of great-playing basses that people bond with and just can't put seem to put down. It may be
safer to buy a super-clean example of an older bass, but you will definitely pay a premium price. You might be better off looking for a well-used, but well-loved T-40, and using the $200.00 difference in price to offset the shipping and customs.
Here's a shot of my 1981 T-40. It looks a little rougher close-up, with some pitting on the bridge and surface wear on the knobs. It's got some dings, but the back of the neck is smooth and the fretboard edges have been nicely rounded and broken in. The bass plays like a dream, and cost me less than $350.00.
I've only had the T-45 a short time, so no pics yet. I don't know if this will help you decide about buying a T-40, but, for what it's worth, I'm seriously considering selling my mint condition Ric 4003 so I can justify keeping the T-45...
