Hi Dale and welcome to the Q&A Board,
The problem sounds familiar, with my 300D (digital rebel) I only get 4 frames in a burst but want 8

. It's a question of buffer size and write speed and if you want more, well, you have to pay more.
Seriously though, while it can be inconvenient to have to wait I certainly wouldn't stop using it because of the lag time. I find it increases my chances of getting a keeper, in particular when trying to get an in flight shot. If shooting at a relatively stationary target I probably wouldn't use burst. When I do use it I do try to do so judiciously, meaning I had to learn to judge when I can afford the wait and when it might cost me a better shot. Of course there are times when my judgement is a little off...
