Tuttifrutti - I think you have the opportunity for a "best-of-both" setup there...
Your S95 with its larger than the bridge-zooms sensor and aperture, has good low-light, high-ISO, quality JPEGs - and RAW. What it doesn't have, is much Zoom, for Images or Video.
The SX30 with 35x Optical Zoom, has plenty of that, and the Zoom also works well with the Std HD Video. From what I've seen, the Video is pretty good quality.
What it doesn't do quite as well, are stills JPEGs - the 14Mpix on the still 1/2.3" sensor doesn't help with that, or with the low-light / high-ISO - and there's no RAW. You can add the SX10-type "Superfine" large file-size low-artifacting, low-compression JPEG level (and RAW) - to the SX30 / SX20 - with the CHDK 'hack' - it runs from an SD card and doesn't harm or permanently change your camera. Do a Search for CHDK, this Forum, if interested.
Or - as Steve suggests - if you don't need HD Video - and 20x Zoom is enough - the SX10 probably does the best Superfine JPEGs of all the Bridge Zooms (my SX10 certainly does better JPEGs than my 30x Fuji HS10...)
The link Steve gives takes you to ample descriptions of the SX10, by Delija, myself, and others. You can also look at the "Show Us Your Best With The SX10" thread - plenty of examples there.
You do have good HD Video with your S95 already - the SX30 would only be an advantage if you need a lot of Video Zoom.
The SX10 is a better JPEG stills Bridge Zoom. However, it does do good VGA Video - 640 x 480 - in the current H264/MOV format. The SX10's 1.4x internal Teleconverter (NOT direct 'digital zoom' - it's interpolated zoom) - is quite usable to a "virtual 28x" for stills, in good light - displayed at reduced size, the images are quite adequate for onscreen or sharing. (There's also 2.3x TC - but that isn't very usable...)
The 1.4x TC actually works better with the Video, as that doesn't use the whole sensor, anyway.
However, the SX10 is either becoming, or has become, a bit of a "collector's item", due to its quite compact size, not being "too obvious", even using the 20x Zoom, and the excellent 10Mpix on 1/2.3" sensor JPEG quality, so isn't as cheap as you'd expect for a "2 models old" camera. (You "can" add RAW with CHDK - but on that size sensor with Superfine JPEGs, probably wouldn't gain much.)
I have a Fuji HS10 - 30x / 10Mpix on 1/2.3" BSI-CMOS sensor... My SX10's JPEGs are a lot better than the HS10's - and the Fuji's RAF RAWs not that much better than the SX10's Superfine JPEGs - they're of more use for correcting light/shade errors, and for low-light / high-ISO, than getting much better actual quality than the SX10's images...
