SP-10 mats are sometimes available at Ebay.
There are countless posts on Technics mats, my favorites are Micro Seiki CU-180, Boston Carbon Fiber mat and Funk Firm (thick).
The Micro Seiki fits like it was made only for SP10 but will cost you a lot. The Funk Firm sounds good but has to have diameter reduced to fit inside the lip on SP10. The Boston needs nothing except put in place and use.
Which sounds best will depend on your taste, the cartridge and even the set up. I think the Micro Seiki is the most dynamic and cleanest but horribly expensive. The Boston is a contender for much less. The Funk Firm is another sound, harder than stock Technics mat but softer than the other two.
Fortunately you can drop a new mat into place, correct VTA and listen for yourself.
