Best Robotic Cleaner for me???

[wazoo]

I have the hook up for a robotic cleaner but my pool store wants to charge me 1500 bucks for one (not sure which one) I have been on this site enough to know that the pool store is the absolute worst place to save money. I am guessing I can get what I need for much less and I bet that ya'll can tell me what is best.
I have a 18x38 pool with a 9 foot deepend ( in ground of course) . Chlorine system.
Just like I tell when I am buying a used car: I want the best most dependable product you have while remaining budget conscious. I don't mind paying for quality but I want it to be worth it.
Thanks for your help.

I have the Active 20 and really like it. It occasionally lands on it's back and gets temporarily stalled on the main drain cover but can free itself. None do steps or shelves well so I wouldn't use that as a criteria.

I have the Dohney Discovery (Same as the S200) and LOVE it.
