I had the Desire HD for a full 18 month term and gave it to my other half when I upgraded.
Although it was heavily modded, even stock it was a great phone. It's relatively old now, but it still is a really solid phone, worth paying the extra for.
If root and ROMs are your thing, there's a really great and active dev community behind it too.
You might not have insurance, but if your phone is that new and on contract, you'll be covered under warranty though so it might be worth giving your network a call and seeing about getting your Sensation fixed?
