120v Silicone Heat Bed Source

Some time ago someone posted a link for a custom silicone heat bed manufacturer. Sorry to ask....but I've searched and haven't been able to find the link. I'd like one that's multi-zoned for small to large prints depending on the print model size. My aluminum print bed is fixed, measuring 760 X 550 mm. I also need it wired for 120V power. I've located mfgs in China but i'd like to find the one recommended here that worked well for them. Can anyone help? Thanks...TP.

My custom bed heater was made by Shenzen Ali Brother Technology.

I found what I needed and placed an order. Bed heater should arrive in a week. Thanks dc42.
