Should I get an Eris or an unlocked Telus? What's the difference?


Ok so at first I had the Sprint Hero. HATED IT WITH A PASSION. I disliked the look (looked cheap and tacky) as well as the button placement was very annoying. I love the way the original Hero looks with the chin and slick colors... Now that Telus has the Hero with the original look I have a chance to get it and unlock it to use on At&T's fast 3G network and still keep the look I like. The only issue is it costs $400 for an unlocked Hero. My only other option is the Eris the buttons are placed fine and it looks 'OK' but the thing is does this limit my options on what I can do with it? I'm talking about as far as testing different ROMS and flashing etc... I know when the Sprint came out, things had to be made compatible with the Sprint version before you could use them etc... But I'm guessing since the Telus version is pretty much the European version with the added US radio, it can accept any mode pretty much made for the Hero... Is this true for the Eris as well or do I have to get Eris specific mods and wait for ROMS to be compatible etc...? Any guidance would be helpful.
