Absolutely. I'm all for clinging to the past, but I am thoroughly enjoying the TOS-R episodes right now. And I watched every one of the 79 episodes during syndication in the early 80s to the point that my dad threatened to destroy all TVs in the house. (it got worse when I discovered videotaping)
As other have said, if they do a re-release for HD, it's gotta be done anyway. If that happens, DS9 would be the ONLY series I would re-buy under the new format. TOS, TNG, VOY and certainly not ENT gets that honor on my shelf. DS9 was the best!
