New here got a question on Single din unit

Hi all I recently brought an Audi A3 Sline 2.0 TDI I love it!! anyway got straight down to buying bits and bobs and soon realized I wanted something a bit more than the single din concert CD player. I have searched the internet to death on double din conversions and it looks very expensive to me.. so I was wondering if anyone here had used one of the single din flip out CD players, I have found a load of them on Ebay that do exactly the same as the double din ones but obviously flip out. My main concern is that it will look naff, does anyone have any pictures or knowledge on them in Audi A3s?

Yeah that's what I have always thought, just looking at saving the pennies! but I spouse its worth it to get the OEM clean look
