Holly I have one of those too.  It's a Hamilton Beach and I got it at Walmart for $70.  I have heard that there were a lot of problems with them where they would just stop working in the middle of cooking but I never had a problem with mine.  I've seen the Magic Chef for closer to $200 but only on sale, it is usually closer to $300.  Before I had a talking one I had a sighted friend who was able to help me put tactual labels on a touchscreen of a microwave and I hav also used the microwaves that you can still buy that have dials and just set them according to the clockface positions and there is a panasonic microwave that has buttons which some people like but it is over $200 I think.
