VarioGPS UltraBip vs ?

At the point in my training where I am required to get a Vario, moving from coastal soaring to inland thermalling.

I want to get a VarioGPS so I can see my flight logs etc, I have discovered the UltraBip which I really like th look of, the other option I can get locally is the Syride SYS'GPS V3. However it's about $200 more than th UltraBip and the only thing I can see that really separates them is a screen. I can tether the Bip to my phone if I really need one. Or I just use the voice feature for my speed altitude and other peramiters (which is my intention).

Basically has anyone got any hands on use with this device? What are your thoughts, do you miss having a screen? Would you recommend it, or would you advise I go a different direction.

I imagine most of my flying will be coastal soaring just due to where I am and the local flying areas.
