£200 for a DVD cam isn't really realistic, unless you find a great offer somewhere. Entry level DVD cams tend to be around £250 (web price).
Note DV camcorders tend to be better value at a given price point; you can get an entry level DV cam fron Canon (like the new MD101, or older MV890/MV901) for under £200, which will produce better quality video than a £250 entry level DVD cam. (If you spend £300-£400 you can get a DVD cam which is better than an entry level DV cam, but it stil won't be as good as a similarly priced DV cam).
Sticking with an entry level DVD cam - I suggest the Panasonic VDR-D100. Prices around £250

Others to consider are the Sony DVD106, or the Canon DC95/DC100.
