Dolphin Dynamic or Poolvergnuegen and PoolBuster?

Okay, my pressure side cleaner is ready for retirement. Part of the problem is that I just don't go to the bother of removing it from the pool. It's to unwieldy to have a mass of hose and plastic to pile up somewhere. So the eating away by chlorine makes these things last 2-3 years at most for me.

So... I'm really tempted by all the positive comments to get a Dolphin Dynamic. It sounds like once or twice a week usage is all I would need. But it's so expensive I'm considering a Poolvergnuegen 4 wheel pressure side replacement and a PoolBuster for any spots it would miss, and pocket the difference. Any opinions?

I have the poolvergnuegen 2 wheel suction side cleaner and while it works pretty good, I wish I had gone with the Dolphin instead. I have solar, so most of my run time is during the day which means the cleaner must be in the pool during the day as well. I would rather run the Dolphin at night instead when no one is using the pool.
