Camera trade-up advice

Anybody know of details of where I could trade-in my K100 body for a K200 or perhaps a K20 (UK or Ireland)?

Would prefer this approch rather than trying to sell and buy seperately.

Thanks for any info.

Very few companies trade in these days and if they do the value will be very low.

I know you don't want to buy and sell but if you want best value that's the way to go. eBay offers one opportunity to sell, but also you can advertise here in the appropriate section.

Thanks John, seems to be the best advice - I'll start advertising!

SRS Microsystems will usually trade, but you're better off selling & buying separately.
