I can't make up my mind

so I ordered a new samsung dishwasher and it should be here on the 8th of may, but now I am rethinking my decision as I bought a detergent booster so my dishwasher now is cleaning better. it also has a seal out of it (it's an old whirlpool model). I am also trying to keep in mind that when we leave the rental we are at now and get a house that we have one to leave here (has we threw the 70s style one out). I guess I am looking for opinions here....
