I have fitted a couple of the Forge ones myself and in truth they aren't much more the a machined OEM shifter. It looks like they mill a slot for the adjustable part and mill off the VAG part number. They do work ok and are more than adequate.
The reason I took off the Nuespeed one was that my wife wouldn't drive the car with it on, not a bad thing I hear you say, but in truth it's much better to comply with the demands and lead a quiet life. It is a very short shift and does take some getting used to, I know a couple of people who have them and really like them.
I have now moved to the Audi S3 OEM part which is even cheaper but isn't as short as the Forge/Nuespeed but does passify the wife.
I don't think Neuspeed offer a side/side kit but when you see the quality of the Nuespeed vs the others you'll appreciate why they are more expensive. I know VF Engineering now make one which again is great quality but more expensive.
