I don't know much about the joysticks you are looking for, but I'll add my two cents.
If you're looking for a specific (and rare) joystick, go for ebay.
If you're looking for competition pro joysticks (or think they would be ok for your gaming plans), there are some for sale on this german online store: http://www.vesalia.de/?V02b0f1458504712 ... 479666b225
They are 9pin ( amiga ) or USB , so make sure you pick the good one.
The USB joystick quality is quite poor, for lobbers like us, still, mine survived approximately 1 year.
The 9 pin ones are ok. Not good, not bad.
And what about adapters (from amiga to USB) ?
So far, I've found 2 reliable places to find some.
The most famous one is the stelladaptor that can be found here: http://www.atariage.com/store/index.php ... cts_id=267
It is pretty expensive, but worth it, all people who tried it say it's good. It's also out of stock very often, and for a long time... right now it seems stelladaptors are available. They work with amiga joysticks for sure !
The adaptator I and dnielsen use were bought from a guy who lives in Canada, here's the link. Send him an email first, to know if he will be ok to build one for you. Much cheaper, works very well:http://www.raphnetshop.com/products/ata ... ory=Gaming
(prices in CANADIAN dollars !)
All in all, I recommend you to find the amiga version of the joystick you dream about, and get one of these adapters for occasional gaming on pc.
You can also check out the online sensible soccer community store http://www.sensiblesoccer.de
I remember them selling parallel printer port adaptors and a few joysticks...
You can also build the cable on your own
I'll give you the link with the instructions, if you're interested.
Also, maybe you'd be interested by a greekstick ! If so, I suppose Alkis has all the info to help you to get one. (forget that... i should have seen your avatar first ! ) .

All the sellers I've mentioned in this message are reliable.
Hope it helps ! At least this info can be a starting point on your quest for joy !
