How bad is mismatched kitchen appliances in a $1600 rental?

[Johann Jells]

I'm freshening a unit: the fridge must go and I'm going to add an over the range MW, both in stainless (got a great $170 deal on an LG MW at the Depot). The white range seems OK, but is now a mismatch. It's not going to keep me from renting because my market is still hot, but should I spend the $450 on a low end SS range and not be a cheapskate?  Been here in a gentrifying area 20 years and it's hard to change management styles.
