Really, a mobile phone! Bloody hell, I was expecting you to come back and say a Canon 60D or something.
If you, or anyone else is interested this is my Da's website http://photo57.turnpiece.net/
I've been surprised by the quality myself. Its one of the reasons I like the phone so much, I don't need to carry my camera everywhere.
Have you thought of using older lenses?
I shoot with a Sony Alpha, but I picked up a cheap M42 adaptor ring on ebay for a couple of quid and got some very nice lenses for next to nothing. They're manual focus/manual aperture, but the image quality can be stunning.
Someone did mention it to me recently, at some point I will be picking up an adapter to get some lenses.
The SLR I've got is an Olympus E400 - the lenses seem to be more expensive than for most other cameras. However I believe I can also get an adapter that will allow me to use other makes of DSLR lenses, (without losing auto focus), so its something else I'm looking at.
I actually tried to sell the camera last year due to the price of the lenses, and someone did buy it on ebay for around ú180. However, after a week of owning it they claimed they'd received it broken (despite the fact that they'd previously left feedback saying "received safe and sound"), yet admitted they'd stuck a sharp object in the card slot. Despite all the evidence ebay found in their favour and gave them a refund, they returned the camera to me (with the xd card slot broken), I complained loudly to ebay and they paid me back, so I ended up with the camera and the money
Fortunately it also takes a compact flash card so I can still use it (just need to remember where the safe place was that I stored the card).
