Sony 55-200 or 18-250?!

I read the review of the lens on this site & am very tempted to get one, especially for the price (£169). I already have a 16-80 Zeiss & a Sigma 70-300, but need something more of a walkabout telephoto lens. The only other review I've read is on Dyxum, where the reviewer is less enthusiatistic. Beginning to wonder whether I should opt for the 18-250 instead, although that means doubling up on part of the 16-80's range. Any thoughts anyone?
