Saved $4 over the Liftmaster-branded 373LM and got the exact same hardware. Zero issues with my HD950.
Chamberlain
Chamberlain's consumer-branded three-button Security+ remote. Identical hardware to the Liftmaster 373LM at a slightly lower price — pairs with any opener that has a purple learn button.
Confirmed-compatible openers, receivers, and the older remotes this part replaces. If your model isn't listed, send us a photo and we'll verify before you buy.

Replaces these remotes
Same internal hardware as the 373LM in a Chamberlain-branded shell. If your opener has a purple learn button and you want three channels, this is the cheapest factory remote available.
Same procedure as the 373LM — hit the learn button, hit the desired remote button, done.
Each Security+ opener stores up to 8 remotes (counting each button as one). Adding a 9th remote will erase the oldest in memory.

Three doors, three buttons, one Chamberlain remote — perfect.
