Agree with dwette on the UHQRs, one-step 45s. Only have a few. Price aside, they take up a lot of space, and the packaging is excessive. For SQ, 45s are only marginally better than well-cut 33s. I don't like to have to get up three times to play an LP. Also, at least for recordings originally intended for 33 LP, the layout for a two-record 45 is NOT what the artist/producer originally intended. I am a fan of hard-bop and the Blue Note Tone Poet series and appreciate that they are 33s, but I think the packaging on them is also excessive. I have a lot of OG Blue Notes from the 50s and 60s that survived very nicely without a gatefold cover. I'd rather have the extra room on my shelves.
