Hi Ray I have the same Quicksilver as you. Have you considered improving it rather than replacing it? First step if you have not done so already would be to max out the RAM by putting in three 512MB DIMMs I picked up some items on ebay: a Sonnet Tempo RAID card; a GeForce 7800 GS graphics card; and a copy of Leopard. Sadly you can not boot from drives attached to this RAID card (I have two drives acting as one volume [RAID 0 - striped] for extra speed) but you can move the Applications folder and the user folders, etc. to the faster volume. The graphics card was the cheaper PC version so I had to flash the BIOS chip with a Mac ROM. Also added a DVD-RW drive and hacked the Leopard installer to make it install on a system with slower than minimum spec. processor. Information on all this is readily available on the net, but I can supply some notes if you are interested. If you want a replacement (used) machine and have the money I would go straight for a G5, it will last you longer and you could max it out to improve performance at later date if necessary. To some extent your choice may depend upon what bargains you can find! Have fun. Best regards Alan - - - - - - - - - - - - - - - - - - > I've decided it's time to buy a new used Mac.
