Blow off valve suggestions
I know this has been discussed many times, but my birthday is this month, and my wife is going to buy me a blow-off valve. I don't know which one to get. On the sound side I would like it to be in the middle. I also want one that won't have any negative effects during idle etc. Bring all Suggestions!!!

The car doesn't necessarily run "bad" when running at 100%. The only problem is that there's a chance the engine will run rich for the 1/5 of a second between shifts. Which isn't terrible. As far as what brand you want, that also depends on how loud of a BOV you want. The GFB is quieter than most, though if you're running at full boost, you can still hear it pretty well. The RFL is very loud, if that's what you're after.
do you want a SHHHHHHHH sound or a high pitch one like the hks ssqv bov? If the former, get the forge bov, sounds really nice. Or if you want a space age laser type sound, get the Greddy Type S 
Here's a short movie clip of the hks bov.

Here's a sound clip of the Forge bov.

GFB hybrid, designed with the wrx in mind. no mounting/adapter plates needed and cheaper than most. I got mine used, but works great nonetheless. with 100% vent you have to adjust your shifting again, it varies slightly compared to the stock BOV. but like Choku Dori said, save the cash, or just have her send your ECU to Cobb for a reflash!

One thing to consider
I have a GFB 100% atmosp...and it tends to have pressure surge..Which isn't good..I've done some research and have found other with the same setup as me that report pressure surge..Plus you have to keep it clean...which isn't hard. I've heard good things about the Blitz

BOVs
It seems like every other thread is about BOVs. If you are expecting a BOV to improve performance from a stock setup you'll be sorry, but if you only want the sound and the cool looking mod in your engine compartment then I think the WORX is the one. Also I like the worx because you can adjust it as you like. i think it has 5 different setting. just my opinion...
