convenction oven

Hello! I have been thinking about getting a countertop oven so I can save some electricity since I only bake a little bit every time. I have been reading some threads on here, but still have some questions.

1. Are there differences between using a convection and a regular toaster oven to bake bread?

2. I am on a tight budget... Would the convection ovens priced around $40 or less do a decent job of bread baking?

Thanks!
