I have a Rigol DS1052E, but I wouldn't buy one today. It's basically old and out-dated. I think the DS1054Z has one of the ugliest front panel designs of any test equipment I've seen, but you can't deny its cost vs. performance value.
I would want any scope I purchased from today to have a gradient display. I wouldn't buy anything made by Siglent unless the seller was willing to open the case to confirm and guarantee that the Siglent problem of factory installed rust was not present.
