Hi Joma, welcome to the forum.
I have a SD Cameo which has a lounger. It wasn't important to me but it was to my boyfriend. In fact, he has never even tried another seat, I can't get him out of it. He says he enjoys it so much that there is no need to move anywhere else. So I guess you are either a lounger lover or you aren't.
I didn't haggle over the price. After looking for a while, I knew that all of the tubs I had seen that size and with those options where all in the same ballpark, so I felt it was a fair price. I guess you never know unless you ask.
Good luck in your search!
