My first Apple laptop was a 2000 Graphite iBook SE 466mhz with FW and a DVD-ROM. I bought it for $300 in 2005, tore it apart, put in an 80GB drive, an airport card, and maxed out the RAM. It went for $700 on eBay.
I then got a 2004 1.2Ghz 768RAM iBook Dual USB for $800.
I wish I still had the clamshell iBook but I needed to sell it at the time. The iceBook still runs great. I also have an old original PowerBook my uncle gave me, but I don't know much about it, it stills runs OS8.
Next up is a MacBook Pro.
