As i have observed availability of red micrwaves in market is quite small. Most of them are only for house hold purposes and the only sizes available are like compact size and mini. Also they are no exactly red but thick red. From what i have seen red does illumiates your kitchen with proper combination n also people with different taste likes them. Commercial microwaves in red color are not available currently in the market.
Most of them are in between $60 to $120. Almost all of them comes with advacence funcitonality as list for the microwave above.
