AVR-Chat

So what's my best choice on an affordable pre-built usb programmer?

I saw a few kits but I really don't feel like putting one together.

Thanks,

Kenny

No ?I haven't played with any fuses I read some horror stories :) 

From my research it said this chip had an internal oscillator so I didn't need a crystal on my target board?

Have you set any fuses to use the external crystal? 
If so, you'll need a crystal hooked up when 
programming the ATtiny (or feed it with an external 
oscillator). 

Best,

You can get an JTAGICE mkII for half price at Arrow electronics. Inside
the U.S., price including shipping is about $160. Whether or not that is
"affordable" is your decision.

Offer is at:

You can beat that price:

AVR ISP II is about $35 at Digikey.
Pololu AVR ISP is $20 (emulates AVR ISP II with other cool stuff).
AVR STK500 is $80 at Digikey both parallel and ISP programmer.

Those are all what I consider very affordable.
