You can get an upscaler for like $30 on amazon, and although I've only ever used mine from 480p to 1080p (with the Wii), $30 may be cheap but it's a huge noticeable improvement.
To scale to 1080i is oddly specific and no one in their right mind would ever want to do that normally, so you may have trouble finding a product that does this. And you do not want to buy "a good one" for $400 if your end goal is to decrease the output quality! You probably can find an hdmi to component adapter, then an upscaler that supports 1080i.
My advice is to research your next TV better. For example, I have an older samsung plasma tv, and it can accept *any* input. TV only "supports" 720p, but I can pump 1600x1200 into it (or higher!) from my PC and it will display the image with no fuss. (I'm aware there are only 1280x720 pixels in the TV, but higher resolutions give me more space on the PC desktop to work with, and you can only notice the distortion when reading text).
I didn't want a upscaler, as that would take 480p and bost it up to 1080i, what I want to do, is convert 1080p to 1080i... So, down scaling is what I needed here

Picked it up a used one for almost nothing, as these things go for close to $400. I guess we'll see how well it works when it gets here. My only wonder if it adds lag, if that is the case, I might get it to work but, wont be able to use it because of the lag...
To answer the question, it's a older RPG, 9" guns... 65". It works great and has an awsome picture but, it sucks that I need to have something like this just to use a console...
Know what would really suck ? If Microsoft a week from now enables 1080i mode after buying this device...but, it's my luck so I am sure it will happen...
I have a CRT in the garage, and it supported both 720p AND 1080i. I'd always pick the 1080i for the better resolution though. (Framerate doesn't bug me quite as much as it bugs others.)
Though I'm honestly wondering how far 4k will realistically go. People are only going to be so willing to re-buy all their movies/TV over and over again. I only took the Blu-ray jump because of 3D. Most of the re-purchased movies are re-rendered animated films. If animated movies got to the point where they could render in real-time on a computer, like a flash animation, I could see it being worth it. But for now, 4k to me is merely an annoyance aimed at football fans who don't really know the difference and will probably watch stretched SD broadcasts without even realizing it.
Yep, the same old question..... People had VHS, and moved to Laserdisk, then moved to DVD, now Blu-ray... It happens in every market, with every type of device, dam think about the music market, remember cassettes ? How about 8-Track ? Do you rember installing Microsoft office from floppy disc ? Yep 43 discs... Same old stuff.
The thing about 4K, it will be a Blu-ray player, so you will upgrade your blu-ray player, it will play blu-ray and 4K, so, your blu-ray/DVD will play back fine but, if you want the newer 4K, then you buy a new disk...
It's happens every 20 years in this market for a full change to a new format, a few people complain but, they accept it for a better quailty...
