As with other large brands (Fender, Yamaha, Ibanez) they have some products that if you are offered one, you should run and hide. They have other products that you would want to consider no matter what it cost.
I'm not particularly impressed with their Rockbass line of products. I really like the Thumb and Streamer products. The only thing I don't like about the Thumb and the Streamer is the neck profile. Warwick necks are often described as chunky and like a baseball bat.
Thumbs and Streamers and some of the higher end Corvettes (Jazzman and another model I can't think of off the top of my head) are what I think of when I hear Warwick's tag line, "The Sound Of Wood". I played a bunch of Warwicks one afternoon many years ago and that's exactly the impression they left me with.
I've never played a Dolphin, but I've had a couple folks who have told me that they are excellent basses. I couldn't get over the look of the thing. When it comes to looks, my all time favorite Warwick is the Warwick Infinity

I played one at Elderly Music in Lansing, Michigan the year they came out. It took incredible will-power (and a waaaay too high price tag) for me to leave the store without it.
Peace,
