i need help to make a good amiga , but i dont wanna spend to much

i think 300 us dollars.

Sounding reasonable, so far...

but i want a ppc.

This is stretching the budget, but not impossible, with the A1200.  The PPC accelerators are a lot cheaper for 1200 than for an A4000.  You'll probably need an upgraded power supply and some other bits and pieces, though, as well...  I'd guess you've already busted over your budget.

a voodo card

This is meaning you need a tower case, upgraded power supply, and a Mediator.  The system by this point is probably going to at least double your $300 budget....

i dont kown if i can get a complete good amiga in ebay for better price

Probably... The complete systems sell for quite a bit cheaper than their parts.  You're still not going to find an Amiga of the spec you're looking for at the $300 range... Probably more in the $500-$700 range.

Everyone uses commodity hard drives and RAM.  They are the cheap and easy parts of the system.  It's the PPC accelerator and PCI bus that are going to cost you.

The Amiga hardware is older... But it's rare, and still in demand by both users and collectors.  It's held it's value incredibly well.  Really an oddity in the computer world.

i just wanna a clasic amiga , i like old cpmputers .

Then all you really need is the base A1200.  Maybe a card with an 030 and fast RAM.  

In fact, if you have much more than that, most AGA games will crash, act poorly, or outright refuse to load on a super-modded system.  Trust me.  There's very few things that work flawlessly on my A4000.  (which is why I have a nearly stock A1200 for playing old games when I want to.)

but why is so much money for a computer that is 10 yeas old .

There weren't that many add-ons made, and in lots of cases there are collectors like you and I that want them.  Keeps the price high.  It's supply and demand.  Not HUGE amounts of demand... But there are simply more collectors than available parts; hence the price keeps going up, despite the fact that the hardware isn't terribly useful for modern applications.

Amiga 2000 is poor quality machine.

It was a good machine for it's time...  Just completely useless to this guy, who just wants to play AGA games.  ;-)
