Convection microwaves are very expensive compared to standard units. A convection microwave oven costs around $430 on average, compared to non-convection models that retail for around $160. The majority of convection models are countertop units.
Users are much happier with these units' performance compared to regular units. The downside is that convection microwaves tend to receive lower quality scores (despite their higher prices).
Sharp has many convection models available on the market, many of which are top-rated by users.
