Well I don't have quite as big a collection as everyone here, but I have quite a bit of stuff and its growing all the time.
This is the main anime section. I try to support the UK and Irish releases as much as I can, hence why I own Manga's versions of the bricks and have all the movies up to Broly (which were on sale on Zavvi so had no problems double dipping) other than the OG movie 4-pack as it hasn't been released here. Proud to have the Pioneer movies too. I like Funimation's season Blu-Rays despite their problems because they have great cover art, the best legally available audio for the Japanese version and nice extras. I also bought Manga's version of Kai Seasons 1 and 2 for the Yamamoto score. I used to have the Dragon Boxes but I sold them to have some money set aside for the new Blu-Rays by TOEI, which will hopefully have everything including the Japanese title cards, NEPs, broadcast audio, 4:3 and be the definitive release.
Thanks to Baggie Saiyan
I now have the UK version of Battle of Gods with the art cards. Really happy with this, I have since placed it next to their Resurrection F Collector's Edition but the previous image is the most consistent picture of my shelves in a while so still need to rearrange the rest on the main shelf. I also have the Funimation double features, which I purchased when I was too inpatient to wait for Manga UK's release.
And some miscellaneous DVDs. The Big Green DVDs from back in the day are nice to have as a funny little footnote in the history of UK Dragon Ball releases. I got Arrival from a seller on Ebay for less than €5, was delighted with that. I'd love to own the rest of the Saban Ocean dub someday, but they would be expensive to collect whether I track down the remaining Pioneer singles or take the plunge on Rock the Dragon, that too is out of my price range. Definitely encourage anyone who wants the set to come down in price to keep recommending Manga UK to license it.
I have most of the manga, but have been meaning to get the remainder of the original 16 volumes, since then I picked up some of the 3-in-1s as they were cheaper and more readily available where I live. Who knows, being the collector I am I may end up having a full collection of the single volumes and 3-in-1s.
Of course I have been keeping up with the Super manga. I plan on getting volume 4 and That Time I Got Reincarnated As Yamcha soon.
Another work-in-progress is my collection of Derek Padula's books.
