Affordable, Root-able, Cricket compatible phone?

[Android Central Question]

Yes I know that is a complex sounding question. Im just trying to get some input on what phones I should keep my eye out for that will work on Cricket Wireless, that are able to be rooted, and at least are able to be found either new or used on a budget (I doubt any more than $150 at very most). I would appreciate any ideas /opinions.
Thanks alot
