With that budget, your choice of DA lenses is limited. If you're interested in primes, I'd go with either the DA35 or DA50, depending on your focal length preference. If you want the versatility of a zoom, either the DA18-55 or 50-200, depending on what range you like to shoot. I don't have either of the primes, but from the reviews I've seen they both seem to be solid lenses. I have both the zooms, though mine are the older versions, and although I no longer use either very much, they are very good lenses (mine are, anyway).
If you want more than one lens for a budget of less than $250, you have a lot of options among F-series and A-series (if you're comfortable with manual focus) lenses. My top choice among F-series lenses is the F35-70, which can usually be obtained used for $70 or less. It's clunky looking and the AF is noisy, but it renders colors beautifully, and is almost like a bag full of primes in a single lens.
Of the manual focus lenses, I prefer A-series lenses for ease of metering and the fact that the aperture is recorded in the exif. The A28 2.8 is available for under $150. I don't have that lens, but it gets good reviews. The A50 2.0 can be had for $50 or less. The A50 2.0 doesn't get a lot of love, but I have one, and my copy is a very good copy. (Actually, my daughter has it right now. Hope she knows where it is, I'd like it back one of these days!)
Hope this helps.
