think I know what you mean............... I bought a six year old Panasonic (with Leica lens) from the boot sale - and got home to find it didn't have a memory card, then had to buy a card reader - then had to buy a charger as well

Although it takes good pix, it seems to have a problem with lines appearing if I leave it on for a few minutes - it's o.k if I turn it off after taking a pic. or two. But I think it takes better snaps than my Fine Pix, which is saying something, because I thought the FP was good.
But having taken a lot of snaps this morning, I think I'm now seeing lines on the Fine Pix as well - perhaps it's the heat wave we're having

Anyway, shouldn't buy cameras from boot sales - it's asking for trouble.
