I have the exact same enlarger and have replaced the base board similar to what has been done to yours, you will never need another enlarger as you now have the best in the world.
The only thing that wears are the plastic hinges on the negative carrier, shown on your baseboard at full stretch. Every couple of years I replace them by cannibalising Ilford 5 litre fixer bottles for material with some sturdy but sharp scissors and a small drill bit.
I thought I had the alignment pretty good, then one day I managed to pick up a Zigalign (I think that is what it's called). The alignment adjustments required were minimal and I mean minimal, but it did make a difference. These enlargers are the only enlargers I know of that allow one to adjust every aspect of the machine in any way possible, theoretical or otherwise.
