Nandric,
The mouse wasn't disturbing, only a little surprising. Most of them have been eliminated by B C the cat. She likes to play with them, bat them around and give chase. Then she lets them go.
They scurry off, but mortally wounded from her claws, they find a place to die. Hopefully, that place isn't behind an unmovable object like a radiator. Sometimes I find them by smell. At first, B C used to bring them to me, but seeing my aversion to mouse, she no longer does.
I have no such aversion to aluminum, the Mr Softee of metals, but it depends on the specifics. It's light weight and rather flexible in thin pieces and I've long said that I prefer straight aluminum cantilevers to tapered, in certain applications.
I agree with Raul in one respect even though I haven't heard any of Brakemeier's products. He hasn't invented anything including the uni-din alignment. How is an alignment an invention anyway? Find 2 nulls along the recorded part and you have an alignment. I used similar alignments 30+ years ago setting up Japanese tables. They were inevitably designed for Stevenson. If you locate the cart at the far end of the headshell slots and increase offset angle you get an inner null of about 63.5mm.
With extremely expensive high end carts, it's hard to see the value. Personally, I think WWIII is just around the corner and a solar or wind powered generator/battery charger for your bomb shelter would be a better investment.
Regards,
