Its always worth looking at the crank bearings, if there is any signs of wear and tear they are worth replacing. Plus if you want to spend a bit more you can re grind cylinders and crank shaft for a few hundred £. you'll have a engine almost back to 0 miles but will have to run in after the re-build.
If all bearing faces are fine and not too much wear on the cylinder it will be fine, unless to looking for more power these engine will keep on going. I've seen many with 200-400k miles.
