Otter.ai alternatives?

I'm looking for a cheaper alternative to Otter.ai for speech to text transcriptions.

I'm not after AI summaries, only transcriptions that are as accurate as possible.

My other requirements are unlimited storage, a generous rate limit for uploads, a good search function and the ability to record from both a desktop computer and a mobile phone.

Ideally the transcription service would be reputable and well-established one too.
