Heh, I did pay about that for an A3000 with all the ram stripped, no keyboard etc. which turned out to have flaky video and SCSI. But I am wiser now. Not much, but a little.
The only flaky thing about my spare A3000 is the 1.4 ROM. The rest is just fine - SCSI and flickerfixer are working, there's 1MB Chip and 8MB Fast (ZIPs). Keyboard and mouse are a bit dirty but working :-)
