My wife recently got a Nikon D70s. She wants a 4gb card, will a low cost one be okay or how fast does it need to be to handle the pictures?

The low cost cards are just fine for most situations. You MAY run in to limitations in taking a large number of shots in a small time period. Such as shooting burts of 5 or 8 images at peak action for sports. I run a D70 and it really does not bother me for most situations. When shooting raw I can pop off about 4 shots in a row, then begin to be limited by the CF/Microdrives speed. Shooting Jpeg increases the number of shots that the buffer can handle even further For casual shooting, say one image every 2-3 seconds, it will not matter at all. If you plan to shoot lots of sports then a faster CF card may be worth the investment. You might also find picking up a 4 GB card for most situations and a smaller fast card give you the capacity when you need it and the speed when that is important.

Each "X" is 150 kBps
The big questions is what is the fastest the D70 can write ?
How big is the on-board buffer ? 4 RAW /12 jpg is what I've heard.
Here's a great resource for you:

From a Photo.net messageboard:
"The highest write speed that you can get for D70 is around 4.5 MB/sec,..."
(on my calculator that's 30X - be sure that is a continuous-write rating)
The card speeds rated usually are Read, then Write-Burst speed, lastly continuous Write, as it recording.
24/96 Stereo is 1.1 Mbps, if you care. (about 8X continuous)
So a 40X should more than cover it, in theory.
