I have had that problem with accidentally programming the AVR for an external crystal. I have an STK-500 and it allows you to rescue the chip with parallel programming. The STK500 is well worth the cost. The only drawback is, I wish it came with ZIF sockets. I'd be willing to pay the extra bucks for that feature.
