Hello,
@barythrin
Thanks for mentioning my blog!
> I can't fully see what data was used
I used (almost solely) the achieved Ebay prices at ebay.com, ebay.co.uk, ebay.de, ebay.it, ebay.es, and ebay.fr. If you know more sources of information I'd be happy to know them!
Please note that the post in my blog refers to a detailed Excel sheet where
there is an entry for every recorded sale containing the price, a date, the market, and some (hopefully relevant) comments.
> As with any price guide I know it can't fully be accurate since it depends on the bidders
Well, it depends on your definition of accuracy
Doesn't a market price always depend on what the market participants are willing to pay??
Euros
I agree on the currency issue insofar as picking one currency leads always to the mentioned conversion problems when someone from another currency zone tries to interpret these values - but that would be the same if I would pick e.g. the US Dollar as a basis (with the admitted difference that you might be happier - but maybe not me
). However, in principle I always store a date for every sale I record, so if I could get a function from somewhere that gives me the conversion rate to a currency for a date the list could be automatically recalculated for a given currency. Hmm, that sounds interesting. Can somebody provide me this data (or even code for
Excel or OpenOffice)?
Amiga 3000/4000 prices
Apart from being a very attractive vintage computer I have the impression that the prices especially for 4000s are that high also because these models together with accelerator cards have still some respectable compute power at least for a vintage computer.

I thought the regular Amiga 3000 and perhaps also 4000 would be so common they shouldn't appear on this list, but the sales figures tell a different story.
Interestingly, AFAIK the Amigas are the only models where there are official sales numbers (published by Commodore Germany Marketing) for at least some models and at least some countries (
http://www.c64-wiki.de/index.php/Amiga). As my criteria for being on the list I use the production number of the Sinclair QL (which shall be about 100'000). In these terms, the Amigas are indeed rare.
Does the PET2001 entry only refer to the chicklet version or the "ultra-common" 2001N with full size keyboard?
Currently, it refers to both, but the detailed listing of the sales on the Excel sheet lists whether they are chiclet or not. Interestingly, the majority of the sales were chiclet ones. I think non-chiclet is more common only if you count 3xxx and 4xxx models.
This having said, I currently collect PET 2001 serial numbers because I want to make some research on the production numbers of this model and because I never saw this information elsewhere. Currently I think that PET 2001s were rare-but-not-so-rare with an estimated number of about 60'000 counting all models.
machines not on the list but which are equally or more rare than the one listed
I am always very interested in knowing models which are rare and I always hope on discussions on this issue so I can extend the list. One restriction, though, that I use, is that I seldom add pure CP/M machines or business-only type of machines as there are so many of them.
