Pulse Oximeter Rec

Hello,

I'm in the market for a recording pulse oximeter with the following requirements, surprisingly hard to find:
-Rechargeable
-Bluetooth
-Sleepyhead compatible
- A clock that you don't have to set every night

Preferable:
- Fingertip (not wrist) version

So far the CMS50FW is the most likely candidate, I've poured over the product websites, but very few seem to have these basic features. Any other recommendations?

Thanks.

The newest 50F models (version 3.7) are not compatible with SleepyHead. The data file format was changed.
