Just pick it up if its 6k. I took the same some 6 months back by paying around 7k equivlant USD. Dont worry about the region. You can upgrade the firmware apart from that my DV600 is in region 3 and it plays almost all the DVD's without any issues.
I would a bit careful here, as I have had some tense moments with Pioneer. I purchased a 686 from Europe, and it refused to play any DVD other than with Region Code 2. When I checked with Pioneer's service centres here in Chennai and Mumbai they told me that they have been instructed by the parent company
not to encourage region code conversion. I wrote to both Pioneer Europe, and to Pioneer Singapore. They both came back with the same answer - Pioneer does not encourage region code change and will not provide any software or firmware upgrade for this.
Yes I know there are other ways of doing the region code change. But such methods are always fraught with danger unless it is backed by the manufacturer as Oppo does. In addition, third party firmware upgrades for Pioneer are complicated. I am also not sure whether firmware upgrades have been released for the 400 and 600.
Is there some confirmation on that 6k price? Also buying a Pioneer, i assume, would mean buying grey right? and that would mean no warranty? So is it worth going for that route?
I am not sure about the price, but yes that price will be in the grey market. Regarding warranty, look at this way. DVD players have become commodity items much like mobile phones. I purchased a Philips DVD player a few years ago for about 10,000. When it stopped working, the service center said it will cost me 15,000 to get it repaired and it will take 8 to 10 weeks as he has to import the parts.
I expect a budget DVD player to for work for 2 to 3 years without any hassle. After that, the best thing is to discard it and buy a new one. Technology would have changed, new features will come in.
On a safer note, I see a number of Pioneer service centers across the country, and they will service a Pioneer product irrespective of where you have brought it from.
If I were in your shoes, I would take a detailed demo, check the region code, and go for it.
