Yeah, you're not going to find an HSPA+ 42 phone for under $300. I'll tell you though, it makes a noticeable difference in data speeds. If you don't mind HTC, I hear the Sensation is pretty good after being updated - before its software update, I wouldn't have touched it. I didn't like the Exhibit II because it has some weird software bugs. I'm really liking my Galaxy S Blaze (I think I've seen them for around $300 new on eBay) which is HSPA+ 42; I'm using it while waiting for the Galaxy S III to launch.
