If it were a single piece of worktop, I would avoid wood like the plague, But the worktop is three 2m lengths of wood - only one of which has the undercut sink & rot in it.
Replacing 1 x 2m length seems acceptable, given that this is only going to be temporary.
Whatever I spend is going to be regretted spend, as I'll be ditching the lot in a couple of years, when we re-do the kitchen entirely.
Are there any restaurant supply businesses in your area? I would look for an old table/countertop section in stainless, cut to size and replace the wood with that.
