Need help with Decision on Blue Diamond

I am going to buy a pool robot this year and want to spend in the $350.00 range and my pool is a 24Ft Round AGP.
I have the opportunity to buy a used Blue Diamond for $300.00 that is 5 years old and in decent shape.

Does this seem like a good system for me or should I consider a Rover Jr, Wanda or something like that. So many cleaners my head is spinning.

Any help or recommendations will be greatly appreciated.
Thanks

I don't know about the other ones you mention, but I have Wanda and she does a good job for my pool.

And I have the Blue Diamond with wireless remote. I don't know how a BD will work in a round. It's really designed for IG pools and mine, being rectangular, "looks" like an IG to it. All in all it's a fantastic unit, but you may want to check with the company about rounds.
