The aluminum ones are excellent. I had one on a highly modified c900, and my local Saabers have used them as well.
The main problem is that they are about $60 now. When they were first noticed, they were $45 and thats a bargain. You can now find a used Forge for about $60-100, so its up to you.
If my current Viggen didnt come with a Forge valve, I would have bought an eBay one.
