Best Sprint phone?

[fishingmedic]

I currently have an Omnia through VZW and will be upgrading my Sprint phone shortly. Was planning on getting a TP but reallly know nothing about any of the phones on Sprint other than the TP and Diamond and don't know much about those anyway, i.e. the good, bad and ugly of the phones. Any recommendations of either the TP, diamond, wait for the TP2, or anything else. I'm also trying to watch my bank account so I need to take that info consideration also. TIA for any help/recommendations!!
