I decided to go with the MindStor 10G. Thats alot of space! I also got the All-in-1 adapter so it will take the Smartmedia from my wifes camera. It was $345 + shipping from d-store.com. Since my PC has a Firewire connection (yippee!) I can Download at 1G/min. It will also act as a card reader when both memory card and PC are connected to it. Since I plan on shooting in both RAW and JPG, it was the way to go.
I still like the 1G MicroDrive but it leaves me with reliability, write speed, and power consumption questions. From what I have read, its reliabilty is 50/50 when used with Nikon D series cameras. Here's hoping you are on the good side of that 50/50.
