DAB Aerial alternatives??

[Scooby]

Dunno if its just me but the chunky DAB aerial base on my GSi doesnt suit it and i was wondering if anyone knew of any aftermarket replacements, Sharks fin type, perhaps in brushed ally im thinking ...if so would it be easy to replace.

I was looking at a shark-fin aerial a while ago, but we need one that has a washer jet included.

I'd be interested to hear if anyone has found one?

Where is the Astra Sport Hatch washer jet? Only ask coz I picked up an Irmscher catalog today and they have a shark fin aerial in there.
