Picked up a ZTE Racer on 3 recently as I am on a tight budget at the moment to replace a phone that died on me (cost of presents for kids, eh?) and wanted to stick with my current network. (Yes, I am a very happy 3 customer, we do exist!!!)
Works well for what I paid for it (£79.99) and am really happy with it so far. Does everything I've asked of it with aplomb. Looked at some of the others and tried some. Wasn't impressed by the LG offering at all. The San Francisco looked good, but I read a lot of negatives about it online that put me off.
Wife has a more expensive Android phone with a capacitive screen and I find myself more comfortable with this particular resistive screen for some reason. And I have used some really bad resistive screens over the past few years, this is a damn good one! Shame the screen is small, but it is very clear and readable.
My only gripe is the battery - at 1100mAh it struggles through a couple of days without needing to be recharged. Oh and the lock button is rather awkward at times, but you get used to it.
What works for me won't work for everyone, just sharing my experiences. Budget phone - does what it says on the tin.
