Yes, please do so. However please note that I tested some of the devices you tested and got other results ... just look for yourself.
Videomaster Professional Video Scart Controller:
- Isolation: Failed
- Sharpness: Slight bleeding of bright/saturated picture areas
- Noise: Didn't bother to test
- Other things worth mentioning: Cheap, dirty looking metal case
Hama AV Selector 100S:
- Isolation: Pass
- Sharpness: Slight bleeding of bright/saturated picture areas
- Noise: Noticable noise added
- Other things worth mentioning: none
Marmitek Connect 236:
- Isolation: Pass
- Sharpness: Heavy bleeding of bright/saturated picture areas
- Noise: Heavy noise added
- Other things worth mentioning: costly, remote controlled but doesn't do automatic switching
Professional 5-Way Scart Video Control Center (Profitec TC-736):
- Isolation: Pass, however ... see below under "Noise"
- Sharpness: Minimal bleeding of bright/saturated picture areas
- Noise: That's a weird one: If only one device is connected to the switch, everything's okay. However if another device gets connected (this other device doesn't have to be running or even be connected to a power supply!) you can see considerable noise in low-brightness 288p/240p signals.
- Other things worth mentioning: metal case, semi-costly
Hama Scart-Switchbox 4/1 and derivates:
- Isolation: Pass
- Sharpness: HEAVY sharpness degradation (see below), ghosting (from time to time I could see duplicates of bright letters to their right)
- Noise: No added noise
- Other things worth mentioning: sturdy metal case, semi-costly, very basic connector-wise

"First image" -> signal from a Switchbox derivate (the Hama Switchbox does even worse!)
"Second image" -> original signal
Bandrigde Premium 5 Way SCART Selector
- Isolation: Pass
- Sharpness: No sharpness degradation
- Noise: No added noise
- Other things worth mentioning: pretty fancy connector/feature-wise; at first I had to fiddle with the Framemeister's Sync_Level setting to get a picture from this switch, now it works with automatic sync ... weird.
Btw I didn't test for brightness degradation since the Framemeister can compensate that without problems.
EDIT: I can't stress this enough: USE GOOD SCART CABLES!!! I recommend the "Goldkabel" ones with the Ferrit cores - they work perfectly and you can get them dirt-cheap on (german) ebay.
