I can certainly see where you are coming from on that one.
An off the shelf / easy to fabricate solution would be ideal.
I have a small foundry near me, they have a small - medium capacity output & will undertake small batch work.
It my prove cost effective to have a small batch of castings made !!
A fair bit of money could be saved if you can provide them with the casting patterns, this is where a good deal of the initial outlay is spent.
