Borgelt B700 variometer: Anyone with experience with this vario?

Good day to All,

I currently fly c the Ilec SN10b computer and vario in my Ventus 2CXM. I would like to update the mechanical Winter vario to an electronic vario. I have been looking at the Westerboer 1010 and the Borgelt B700.
I do not want to replace the Ilec SN10 with another computer/vario combination, as that would be too great of a panel and plumbing job. I'd rather keep it simple by exchanging the Winter for a very good electronic vario. It does not need speed to fly and all the bells and whistles. Just a great electronic vario, preferably without the need of a total energy probe.
I called Sean Franke to discuss the Borgelt B700. He states that it only has a pneumatic connection for the TE probe, and does not need a capacity bottle to function. I've checked the installation manual by Borgelt, and that is indeed true.
The Westerboer needs only static and pitot to function. I understand the nature of this type of vario, but am stymied by the Borgelt.
Does anyone have experience with either of these varios? Recommendations?
Thanking you in advance for your inputs.
