I have a PD9260 and am very happy with it. I bought the pendant since it was only around $15.00. It doesn't give you a lot of information since it only has a single led. You have to look at how it flashes to see what is happening. I do like the feature of being able to force the system to bulk charge mode with the pendant.
If you do decide to go to an AGM or SLA battery you can open the case (You have to drill out pop rivets) and change a jumper to set the proper charge rates. It lowers the charge voltage and eliminates the periodic equalizing charge.
